SOUND SYSTEM
Entering the secret code
When turning the sound system on (in the
event of code request), the display will show
the word “CODE” for about 2 seconds, fol-
lowed by four dashes “- - - -”.
The secret code comprises four figures from
1 to 6, each corresponding to one of the
dashes.
To enter the first digit of the code, press the
corresponding key of the preset stations
(from 1 to 6). Enter the other code digits in
the same way.
If the four figures are not entered within 20
seconds, the display shows the word
“CODE” for 2 seconds and then fours dash-
es “- - - -”. This is not to be considered as an
incorrect code entry.
After entering the fourth digit (within 20 sec-
onds), the radio starts working.
If a wrong code is entered, the radio sounds
a beep, the display shows the word “CODE”
for 2 seconds and then fours dashes “- - - -”
to warn the user that it is necessary to en-
ter the correct code.Every time the user enters a wrong code,
the waiting time increases gradually (1 min,
2 min, 4 min, 8 min, 16 min, 30 min,1h,
2h, 4h, 8h, 16h, 24h) until reaching a max-
imum of 24 hours. The waiting time will
be shown on the display with the word
“WAIT”. When this goes off it is possible
to start the new code entry procedure.
Code Card
This the document that certifies possession
of the radio. The Code Card contains the ra-
dio model, serial number and secret code.
IMPORTANT Keep the Code Card carefully to
be able to give the related data to the com-
petent authorities in the event of theft.ANTITHEFT PROTECTION
The radio is fitted with an antitheft protec-
tion system based on the exchange of in-
formation between the radio and the elec-
tronic control unit (Body Computer) installed
on the car.
This system warrants the highest level of se-
curity and prevents entry of the secret code
every time the radio supply is disconnected.
If the result of the check is positive, the set
starts working, whereas if the comparison
codes are not the same or if the electronic
control unit (Body Computer) is replaced,
the device informs the user of the need to
enter the secret code according to the pro-
cedure described in the following paragraph.

SOUND SYSTEM
MP3 MODE
In addition to standard audio CDs, the sound
system can also play audio files in MP3 for-
mat. Sound system will operate as described
in the previous section (“Sound system with
Compact Disc player”) when inserting a con-
ventional audio CD.
For optimal playing use only top quality CDs
mastered at a speed as low as possible.
MP3 CD files are structured by directories,
with sequential lists of all directories con-
taining MP3 tracks (directories and sub-di-
rectories are all brought to the same lev-
el), directories not containing MP3 tracks
cannot be selected.Technical data and operating conditions for
MP3 files are as follows:
❒adopted CD-ROM shall be mastered ac-
cording to ISO9660 Standard;
❒music files shall be renamed as “.mp3”
otherwise they cannot be played;
❒sampling frequencies are: 44.1 kHz,
stereo (96 to 320 kbit/s) - 22.05 kHz,
mono or stereo (32 to 80 kbit/s);
❒it is possible to play variable bit-rate tracks
(files).
IMPORTANT Characters: blank, ‘ (apostro-
phe), ( and ) (open and closed brackets)
are not admitted in MP3 track names. When
sampling MP3 CD you must not use these
characters to name files otherwise the sound
system will not be able to play it.
