This page serves mainly for people, who already have this phone and want to know
as much as possible about it.
Also this page doesn't describe how to use it (you can read the manual you bought with phone).
Here I will write something on the phone features and its major and minor bugs.
If you are making plans about buying the phone, I won't to have bad influence on this,
as you can get the feeling this phone is bad.
It's not the truth, but I simply wil not describe mobile phone positives (all the functions
mobile has as works right) too much.
I create this page also because during phone gradual checking I find out
lot of interesting things, which wouldn't be good keep in secret.
Many pieces of information I mention here I find out with method
attempt-error, so some of them doesn't be valid always and everywhere.
I will describe my experience, which result from firmware version 18.104.22.168/4,
SAT* C320 and browser version r015u+w6+11. Some bugs result from lower firmware version,
probably 4.4.x - I didn't know the code for firmware version detection these days.
As far as some mistakes occur on older fimware versions (I notice it there),
they are written by experience other people and mostly occur on firmware version 3.x.
Because this phone has close relationship with Sony CMD-J6, it's possible
that some pieces of information are valid also on that phone - but definitely I cound't say.
Some technical details are carried from other sources - these sources are
listed in the footer of this document.
Information on this page are published regardless of their pertinent patent wardships.
Products names are used here without explicit free usage permission so they can be
the registered marks of their owners and organizations.
Unfortunately this phone isn't too stable, freezing or reset occurs
about once a week, but there are also periods, when mobile phone resets itself
more frequently. I haven't got the reason why it happens yet,
but it have happened to me in these circumstances:
writing messages by T9 dictionary
- reset or freezing
during incoming call (when somebody is just calling me)
call (during my dialling - occures especially
when dialing number not allowed in Fixed Dial Numbers)
while playing Bananas game
while making phone power down
You can recognize reset by screen becaming more dark or blinking
(sometimes even screen shrinkage into one horizontal line in the center),
resulting conkou and switch-over into emergency state,
with its net searching and also "white-hot" SIM card.
During reset there are erased all messages stored in phone (both sending and
receiving on display) and "Last Message", so if you are just writing SMS
you can became angry soon.
While beeing frosed your mobile phone ignores keys press and Jog Dial
press, so you can get respond only for rotation its wheel.
You are not able to switch off the phone normally, the obvious way is removing and
and re-inserting the battery.
I've discovered better way how to do the phone reset (see chapter
Howto make phone reset).
Sometime you can see really extraordinary behaving, but exeptionally only.
It's happened to me: my phone beeing in emergency state made powerdown itself,
but without the screen becoming black, so it was still displaying its contents,
with time stopped.
After my long red button press, the phone switched itself on normally.
Another excetioptional case was, when I stepped in the message list,
but I wasn't able to read any; the machine didn't react. Switching off and on
Loosing net connection:
From time to time the are situations, that although phone looks like
having standard signal, it is impossible to dial from or call in.
This state is only temporary, definitely will help switching off and on,
or simply leaving the phone alone, it will reconnect to net itself .
Double operator's name displaying
Mobil phone shows 3 lines in emergency state: current net, time and
my operator (whose SIM card I have). Last row has to be shown,
only when being in foreign net over roaming. With older firmware sometimes
there are shown all 3 line at home net also, for example notice PAEGAS CZ
is displayed twice.
This however doesn't need to occur having other home operator.
This mistake shouldn't be in firmware version 4.6 (?). As far as you can
see operator twice, new firmware upgrade will be sufficient correction.
Right margin in Sand Art game:
Sometimes there are situations in Sand Art (sand dropping) game,
that sand could get across right screen margin.
In this case the sand stopped dropping and it is impossible to start again.
One solving is middle button press, game saving and reloading
(saving and reloading game isn't in manual - see chapter
The error there however keeeps place, I haven't discoverd how with to beat it
(try phone switching off and on). Either it or will be going right or not.
This error hasn't influence over other function phone - for instance
it is possible to finish the games whenever.
Call interupt 'cause signal loosing:
This error don't occurs too often, just imagine: you are going by tube,
somebody is just calling, you are going to answer it, but before completition
you will get out of reach signal. This lost talk wouldn't be stored however and
if you haven't seen who did the call, you probably wouldn't know never.
While you are sending e-mail over Microsoft Mobile Explorer, you can put in
as many as 800 characters. If you would acknowledge the message and reenter
the "Body" field again, there will be displayed only 649, sometimes 660
Meanwhile I don't know unfortunately, whether really all 800 characters
will be send.
Private tunes playing:
It's possible to record 5 two-seconds and 5 10-seconds tunes into the phone.
There is minor bug however, when you already have your sound recerded
and you are going to play it in the recording environment.
So you go into a place "My ringers" and choose appropriate ringing.
Playing the sound first time, you hear: it's about bit shorter! Repeated
playing makes sound be heared normally.
Voice mail with Fixed Dial Numbers:
Voice mail number is stored in the phone all the time and could be choosen
by long button "1" press. But if you have choosen "FDN Entry Only" in
"FDN Phonebook", it's impossible to call voice mail this way!
It's so, although its number is stored as fixed (and hence permited).
Asterisk-prefixed numbers calling:
With older firmware (about till version 3.X) it's possible, that no
number beginning with asterisk could be dialed. I haven't tried to break this,
because I don't have such a firmware, but perhaps there is no other choice,
than calling an alternative number not beginning with asterisk.
Bad called numbers displaying:
Sometimes you can see, that "Call History" shows, that you got ring or called to
somebody, who you haven't know before. How it is possible?
If you call someone, someone calls you or you only "ring" someone, this call
will be written into phone as an event. This event consists from several parts:
phonenumber, time and date of call and position in list,
which corresponds to telephone number.
And this very position can cause mistakes. If you would erase this name
from the list, there will no name displayed here. As soon as you insert
somebody else's name, it will lie down just at this free position.
Event thereby changes - new name will be shown, but with right number.
As far as you are then on doubts, if it is the right name, than for this event
enter "change" and simply start the call.
Right name from list will be displayed than.
When you have recorded some sound, you have this sound in the ringers list also.
From time to time it happends however, that during change from recorded sounds
to normal ones you make the phone mad: you can hear jerky recorded sound
together with playing normal built-in tune.
This behaviour is however rather "cosmetic" bug, there is no influence
on other phone functions.
Random uppercase/lowercase letters mixture:
While writing text without T9 dictionary with you can see sometimes, that phone
itself randomly switches uppercase letters to small ones.
With older firmware it occurs at the beginning of writing.
Status bar displays "Abc", i.e. first character is in uppercase,
but nevertheless the first letter is in fact in lower case.
New firmware versions have other bug - when you type lowercase letters ("abc"),
you type a characters and at once switch 1st uppercase ("Abc"), phone
itself switches to lower case.
The only preventions of this are either delay on about half second,
till phone stop waiting for repeated keystroke and it will want new letter
already; or typing always with T9 dictionary.
With typing there is other bug also. While having set "Abc" and you delete
a character, all the time "Abc" is displayed, but now you will type all
With T9 this error occurs only in the case, when deleted character is space.
Alternatives selections in T9 dictionary:
While writing messages with enabled T9 dictionary, there will be displayed
the most frequently used word always on the first position.
To use other word, you select it by Jog Dial (wheel). As far as you
focus the word requested and press '0' (space) to contine, the original word
you have choosen will be replaced by the first one, the most frequently one.
Then to correct selection the focus is not enough, but pressing Jog Dial
to acknowledge is necessary also.
This bug was fortunately in former firmware versions, in new ones is not.
As far as you have you the phone with this bug, upgrade the firmware.
Available T9 dictionaries list:
Selection list from available T9 dictionaries will be displayed only in case,
when on our phone you have choosen the language, which has its own dictionary.
For example beeing Slovakian with Slovak language set, you cannot type
with T9 dictionary for any language, because Slovak T9 isn't in your phone
(somewhere perhaps yes, this is only for instance).
I don't know, if that isn't the purpose, but virtually it is a nonsense
SMS last character:
While writing you can press "#" for additional characters showing.
As soon as you have only one character left, some characters your phone
don't offer. They are these: backslash, euro, tilde, circumflex, both right
and left complex parenthises, right and left square parenthesis,
vertical slash and enter.
However there isn't reason for this, because all these characters
take as much space as the other.
Bad names sorting:
When you insert SIM card from other phone it could happend, that some name
get wrong order in list and therefore it is impossible to search for it.
You can correct this by "Edit Name" and acknowledge.
Name will be sorted right than.
long tune together with powerdown:
If you choose "Bebop" or "Alhambra" as an ending tune, the music is so long,
that the phone will switch off before the tune ends.
In practice it looks as a simultaneous start sound playing together with ending
animation. When animation ends the tune plays about 1 second with black screen,
then tune aborts and mobile phone switches off completely.
You can count this error as user mistake - he has to select other sound.
The phone would better do not offer these two tunes at all.
Low message loudness:
During telephony it is possible to quickly change the loudness by Jog Dial.
As far as you lower the loudness and finish the call, phone will remember
this loudness and for next call will be the loudness alike.
But also the sound incoming call will! (Proportionately
how much you reduce the call loudness.)
To prevent this always turn loundness on maximum before finishing the call.
If you have finished it yet, so briefly start dialing some number,
increase a loudness and immediately hang on.
Incoming call during message writing:
There is a bug, while writing message just somebody calls you.
You can see on screen incoming call, but in top left corner is white space
with blinking cursor in it. Ridiculous is, that when you further continue
typing or deleting with red button, cursor moves normally!
You can leave this state either by middle button presing or by erasing all
all imaginary characters (fortunately not more than 5) and then you are able to
answer the call.
It doesn't matter, whether you write with T9 dictionary or not. Error has
the same scenario and characteristics.
Erasing past entries in scheduler
You can get this error if user clicks middle button in scheduler, chooses
Delete and Past. All old records are erased normally, but
if there are some comments in the next month, these days will be underlined
in actual month. Count of underscored days correspondis with old entries count.
This bug disappears either if user enter the same month once again
or he (she) goes over these days with cursor.
This bug hasn't influence on functionality, nevertheless is confusing.
When the phone has bigger power consumption, it could happend,
that for a short time display becomes black and then becomes lighting again
- phone does blink in a matter of fact. It isn't serious failure, it has no
influence for other phone functions.
You can get this error often during sending SMS and during incoming or outgoing
The phone has a little delay for majority of operations - beeig in menu
as you choose entry with Jog Dialem you can move with cursor about half second.
Errorneous display s for SMS selection. Beeing in this dishes, you choose that
you want to read some SMSK and just move the cursor down, you will get
the message, you have asked for. But after re-pressing the wheel
the status bar displays on the top a name and info of the message,
you subsequently touch with cursor!
It's necessary to point out, that thereby the error finishes.
Both deleting and answering works well for the right message
you are have choosen.
Howto make phone reset:
I have discovered out 2 ways how to restart the phone (i.e. return into
emergency state, searching net, "red-hot" SIM card).
First way is (it isn't possible in version 5.x): write SMS with lots of ENTER,
store it as "Last Message" and then start writing e-mail. There call out text
over Last Message so long as there will be at least 200 enters in e-mail. Now
after e-mail acknowledge, phone returns into Microsoft Mobile Explorer, the it
will think for a moment, then display will blink and the phone will make the
The second way is little similar to
bug in Sand Art game - either function
it works always or never. So if the error "works right":
Write some message with active T9 dictionary in any language. Press '1',
now make move by wheel to any character (You can finally leave the stop
character as is, but you must make at least one turn by wheel - this sign
do not acknowledge, only do the shift over it!), then write '7'.
When you press any key from '2' into '9' now, phone will write nothing,
but the display will blink and the phone will reboot.
This error "works right" on firmware 22.214.171.124/4.
The third way id possible only na firmware 5.x: Go to Settings ->
Preferences -> Select Network and now press middle button. This is
Tricks for Phone
Adding new word into T9 dictionary:
As far as you find out that your dictionary doesn't contain some word but you
would like it there, so do this:
Disable T9 dictionary and write word normally by keys.
Then is sufficient to do the acknowledge of writing text (press JogDial).
This action will process the whole text and all the words, which aren't
in the dictionary will be put into it.
As you woun't acknowledge this text for some reason, re-enabling the dictionaryi
is sufficicient also. Again there will be stored all the unknown words.
Now the word is stored in dictionary (namely in all languages) and will be
- only few words will be really inserted, after then the new word
overwrites the least used one
- if dictionary offers other variants, it never puts new word
to the beginning
- word woun't be offered until complettely typed (if dictionary
offers other variants)
Note: Unfortunately this method don't work always. For example word "zvonim"
into Czech T9 simply can't be put. It's possible to put in this word for other
languages, but in Czech with never be offered.
The word can contain diacritic - when writing somewhere, where accute characters can be,
the word with accute characters will be offered. In other case will be offered
in shape without accute. As far as already such word without accute exist,
only the existing word would be offered.
There is a question also, how to efficiently delete the word. One way is to put
into the dictionary as many other words, that they with overfill a memory and
so this word will be lost.
If you want to erase all the precept words, simply insert other SIM in the phone
(original SIM card you can insert back than).
How to use shortcuts:
You can recall numbers in the phone directory by so called shortcuts.
To do this in emergency state write serial number of the name in the list and
cross character (#) then.
First 9 serials numbers are quite clear - they are stored in the list directory
just under phonenumbers. Other serials corresponds to the names, that are
stored in SIM cards (not in the phone!) and sorted by creation time.
So if you insert the first name, for example "Smith" into SIM card, its serial
will be 10. After inserting the name "Bart" into SIM its serial will be 11,
because although its enlistment is at the beginning it has been inserted later
You can detect the serial number simply by clicking the name, in detail
selection you click the phonenumber and finaly you choose "View".
Sending image message from other phone:
The following facts I have found after sending lots of messages and making tests,
so I don't expect you get them normally.
Sending pictorial and sound message on this phone means virtually that after
SMS message are put in 7 additional characters, which say to the same phone
type (here Sony, which all models I don't know, on J5 and J6 it definitely will go),
what a picture and which sound to use. So it is impossible for example send
a new picture, because only picture and sound codes are sent, which must exist
in target phone already.
It means also, that for message itself there are only 153 charecters left.
Sending code diagram: Message(PPXSC)
Two bytes of picture code
Probably reserved byte
Byte for sound code
Checksum of previous 4 chars
Picture codes are for similar pictures completely different; pictures list with
theirs codes are listed below.
Reserved byte can have any value, check total must be adjust accordingly.
Phone itself arrange here always zero.
Sound codes are numbered from 0 to K. Numbers
are ordered 0-9, next A-Z
and then a-z. Then what in decimail is10,
it is here A, what is decimal 4, it is here also
4 etc. If a meggage is without any sound has code 0,
the first sound is 1, second 2 etc.
Ckecksum is computed by addding individual bytes both codes.
For example if picture has code 11 and sound 09,
must be add up 1+1+0+9=B, because both individual bytes values
and checksum have the same representation as a sound code.
Final shape should be (1109B) then.
Empty picture - message will be without it (two zeros)
Tee-pot with cup; is showed as the first in selection
Boy in car
Hare with phone
Boy sleeping under tree
Using codes above we can send pictorial and sound messagess also from other
phone types and if necessary from e-mail also. Sufficient to this is to know
codes together with ability to calculate checksum only.
If there is a bad checksum, message itself will be normal with its
"header" in parentheses. With correct checksum but with bad picture or sound
code will nessage not contain bad element. You can try this simply
when you write on this phone (Sony CMD-J5/J6) with Text Only message type
these codes at the beginning its text, then store the message and view again.
If you get it with picture and sound, you just succeed in this system.
Theoretically phone could contain picture or sound, which it is impossible
to call up normally, but practically it's very lengthy to examine this. If
anybody have the taste and would find something, what isn't normally available,
I will be very delighted, when you let me know.
Possibilities during telephony:
During telephony you can do these action:
Activate loud listen in
1. Press middle button and choose "Loudspeaker"
2. Move left switch on phone up (as with profile change)
Switch off the microphone
Press middle button and choose "Mic Off". Similar to switch on.
Get into phone main menu
1. By middle button choose "Main Menu"
2. Press Jog Dial wheel
In this menu you don't find sounds, WAP and e-mail. You can however start
another call using phone directory. Now you can speak with two participants
and swithing between them. Unfortunately they can't mix together.
Strange is, that you can call somebody while playing game.
Third man calling
You can call somebody either by phone directory or by dialing number.
If you want to call somebody from the list, use menu (press wheel),
choose "Phonebook" and make a call normally.
If you want to dial directly, type the number normally while speaking
and press green phone button as usually. This way isn't so efficient,
because when calling lines with additional nubers for selections,
these numbers are mixed with phone number (Except with disabled parameter
Settings -> Call Settings -> DTMF Tones).
Get into SIM Toolkit
It could be done the same way as from emergency state, when not speaking;
by long middle button press. If you have typed DTMF tones before it,
you must clear them by short middle button press before you can start
going into the SIM Toolkit.
They are available using middle button or main menu
While you are using DTMF tones (typing numbers on one's behalf confirmation
different action) and you would like them rub out, press the middle button.
Hiding SIM card numbers:
If are you use your phone somewhere, where you will somebody not call from your
phone or if need to hide any numbers in list below code PIN2, do it this way:
Numbers (names) which you want to hide must be stored in SIM card (not into phone).
Then go to the "Phonebook -> Phonebook Menu ->
FDN Phonebook -> FDN Entry Only -> -set PIN2-
-> On". Now its possible to call only numberss they are in
FDN Phonebook - one menu back. This numberes it is possible to insert
and change below code PIN2 too.
Beside that you can call on restricted number count (count depends upon SIM
card) there are also hidden all entries in the list they are stored in SIM card.
Reason of this i don't know, nevertheless it is quite reliable, namely when
inserting SIM cart into other phone.
There is error while having set Fixed Dial Numbers in voice mail (see
with Fixed Dial Numbers).
Efficient mumber searching:
It is possible to find phonenumbers in the list by different criteria.
Here are you listed basic methods together with lesser-known ones.
offered by default - Phonebook -> Search ->
default offered too - Phonebook -> Search ->
by group - only groups present in the list will be diplayed
1) This method isn't much efficient, but it's possible. In emergency
state write codes "number#" step by step (see
How to use shortcuts), while phone accepts them.
After entry display shows phonenumber. Start dialing this (with immediate
abort) - name will be displayed.
This way is not suitable for frequent search 'cause it is quite complicated
and takes lot of time. 2) Remove SIM card from the phone and put into other phone, which
has no name in memory (or it can't store them at all). All the names
will be nice listed then.
This way virtually doesn't work. Only exception is, you know the whole
number - after dialing you will see the name.
Note: Theoretically it is possible type last 7 digits -
name will be shown too.
How to insert name without phonenumber
Sometimes you need to put in the name with some note, but without number.
Numbers are required by phone, otherwise nothing is stored. You can write
***, but it doesn't look nice. What about it?
It's easy. Go to Phonebook, select Phonebook Menu,
then New Entry. Name must be stored in the phone, not in SIM card!
As a number write sign + (long hold 0) and acknowledge it.
Now you input the name. With this name no number will be stored!
Name record it's impossible to copy - phone writes error Unregistered.
This trick only with new entries - if you edit number to +,
really sign plus will be stored.
Because this is as a matter of fact error, it doesn't need to work all firmware
versions. On my version 126.96.36.199/4 it surely goes.
Because there is very bad games description in the manual you must find out the
games control yourself.
Goal of PicPuz game is a picture assembling. If you would like numbers
as a picture parts press middle button (button between green and red buttons)
during playing the game.
Hardly anyone knows that Sand Art game can be saved. After middle
button press you get two icons. Left icon (dart directed in)
saves the picture, right icon (dart directed out) loads the picture.
As a picture will be saved only the sand which already fell off.
Pictures created in Sand Art game are impossible to use as a phone background.
The only way how add new background is to use some software over a cable.
Codes for phone:
I know these codes for my phone:
displays 15 digits of identification (production) number
*#000# *#0000# *#00000# *#000000# *#0000000#
sets the standard language given by operator (i.e. in my country Czech)
in the manual is written only number *#0000#, but in fact all codes work
set a language of corresponding state code (for exemple *#001# or *#0044#
details see chapter State codes
displays firmware version in phone, Sim App. Toolkit (SAT) and browser
displays operator nane which blocks the SIM card and number of unsuccessul
attempts to unblock. Menu could be scrolled by the wheel.
I don't know what it will do, as only the phone with older firmware accepts
the code (not for me).
This code you can activate only when isn't SIM card in the phone.
It set security code to 0000. It's good when you forget this code.
In more cases you can pay for this operation in service the same price
as unblock! So it's good to know :-)
This code you can activate only when isn't SIM card in the phone too.
It destroys all data from phone - phone book, sounds, data in scheduler etc.
This is useful for sell phone to other person.
Performing different actions (different unblockings) by XX (copied from
English original - untried):
Network lock (normal unblock of more operators)
SIM code lock
I personally strictly discourage to examine, because for exaple for Network lock
you have only 10 attempts left! You can lose pertinent guarantee also.
PIN change with knowledge of old PIN
PIN change with knowledge of PUK code
PIN2 change with knowledge of old PIN2
PIN2 change with knowledge of PUK2 code
network password change with knowledge of old password
These code you must write so that the last character will be hash character.
If you write the code badly and then correct some previous charecter by cursor,
the code will be not accepted.
Code is accepted immediately when written, without call button press.
If there isn't SIM card in the phone, or the phone is blocked against SIM card,
it is possible to order only codes *#06# and *#simlock# and it is impossible
move wheel by Jog Dial while typing them.
Codes marked red are valid in other phones also. Interesting things: for code *#release# phone accepts more
hash characters at the code end also. When you type *#releas# return to
the last digit and finish the code "e" (by 3). After typing hash
in the end phone accepts the code, but nothing is displayed. At the end could
be any number of hash characters. They have no special meaning, but it strange,
that this works only for hereof code.
With locked keyboard you can light up the display by green button press,
and become dark either by any other button or by 20 seconds waiting. If you
press red button, phone will become dark after half of second. By pressing
other button as red one or green one will display become dark instantly.
Make light for versions 5.x works only in case you have set lighting on.
You get into SIM Toolkitu from emergency state by long middle button
Long wheel press works a little as red button. You can escape from menu
by it. Exceptions are in telephone directory and in calling list, where
long press works as green button; during text writing - it only deletes the
text, but doesn't escape and in games - there the phone responds to wheel
press instantly without waiting for wheel release.
To service numbers you can get quickly from emergency state by long
Jog Dial press
You can get latest message by middle button and "Last Message". This works
during writing messages and e-mail only.
The sign + before the phonenumber you can type by long zero press.
It is possible to send SMS to display analogous to message acknowledge.
You can set it in Messaging -> Settings -> Memory Class
by choice "Screen". I do not recommed to use this setting for confidential
or important data - they can be erased by mistake from display when
receiver not expect them so he doesn't notice that something had arrived.
Switching the phone off is possible by very long red button press, so it
is not necessary to use Jog Dial confirmation.
Its difficult to detect the exact moment when recipient phone is ringing.
If both you and recipient are in normal signal reach, you can count
how many times blinks headphones icon (top left). I have examined calls
from Czech operator PAEGAS call to (Czech) EUROTEL - phone start ringing
after 7th blink, and to (Czech) T-Mobile or (Czech) Vodafone the phone start
ringing after 10th blink.
For repeated ringing to somebody are two button clicks enough -
the first is from emergency state by green button into last call,
the second click will be again green button for calling.
It's possible to escape network list quickly into emergency state
by using middle wheel.
While scrolling in main menu it's impossible to obtain any message.
It arrives only when you stop browsing through the menu.
Incoming call arrives normally.
The same is true ohile scrolling the list of incoming/outgoing messages.
Lighting phone display become dark after 20 second inactivity.
It's possible to have for 1 day as many as 10 entries in sheduller;
days range is from 1.1.2000 to 31.12.2099.
If discrete profile is set then any SMS arrives with unchanged sound!
Ready alarm-clock doesn't ring on switched-off phone.
While recharging the switched-off phone event from scheduller will be shown.
However phone will not beep.
Both received "normal" messages and stored ones are saved in SIM card,
message acknowledges on-display messages are saved in phone and are erased
after switching the phone off. You recognize these special messages by
less highlighted (grey) icon.
Combine vibratory with normal ringing isn't technically possible in this
phone - battery not vibrate, but loudspeaker do.
When you have assign private tune to arrival message and you are just
playing some private tune when a message comes, it will not play your tune
but the standard one (i.e. "Wobble").
If somebody gives you very short ring and you answer it ("lift up") before
real connect (without talking and without caller money lost), then the call
will be saved both as missed and received together.
If it is possible to use use middle button somewhere then its icon will be
shown in the top right corner. This is not true: in emergency state, during
calling, while playing games and in world map.
While reading e-mail phone is able to save as many as 2 kB of text in memory.
Number 112 call is possible also before setting PIN (by typing there, where
PIN normally is entered: 112 and pressing green phone button) and also with
missing SIM card (the same way).
Majority of operations are performed with delaying. When you for example
adjust the contrast and acknowledge this, you may continue changing it
for about half second (finally is set the one you acknowledge).
The same happens in messages selection.
Phone contains 20 ringing tones; 15 ringing tones for SMS, signalling
and scheduller and 1 special one for any event + choice without sound;
10 ringing tones for switching on an off and 1 special one for any event
+ choice without sound; 20 sounds for multimedia messagess + choice without
sound; 1 sound for time beating at whole o'clock = total 61 sounds.
Then there is 12 pictures to multimedia messages + choice without pictures,
22 languages, 317 networks (from preferred selection) and 30 caller groups.
Protective phone cover:
There exists cover for Sony CMD-J5, but too reduces the sound. There is too
tiny hole for microphone (you speak into) so small miscpacing cause you hear
nothing. It's however possible to cut out. Worse problem is with small
reproductor on back side of phone - for all the ringing. Phone itself is loudly
only a few, and because on same place is edge of belt holder it's impossible
to fix the place.
Nevertheless I warmly advice to use the cover, because convex display tends
to harm quickly.
Unfortunately I haven't tried software mentioned because it needs cable which I
have't. But is applicable for professional deblocking.
From emergency state we can quickly change language by setting
*#00state_code# (see chapter
Codes for phone).
What what kind are these codes?
I did the job to examine all codes myself - you see the result here.
I've find an error also - *#00421# fails your expectation Slovak,
but sets Czech.
There can be more zeroes in code *#00x# also - max 4 to 6
depending the language.
Note: When setting the code *#0000# (zeros can be 3-7 digits) will be
set implicit language built in SIM card. In my country it will set Czech.
IMEI digits meaning:
Here I explain individial IMEI numbers, which are obtained by typing
the code *#06# in emergency state:
First 6 digits
Homologation type code of wireless phone, serial model number
(Type Approval Code - TAC)
Next 2 digits
final assembly code, serves mainly for producer
(Final Assembly Code - FAC)
Next 6 digits
serial number, which rise by production individual phone piece,
while TAC and FAC are equal for the same model lines and series produced
in the same factory
(Serial Number - SNR)
check or spare number - depends on producer decision
(SP - Spare)
There are no other sypplements and accessories (for example: barter cover,
change of below-lightening, new games and addition software) Sony genuine.
