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 sec-
onds, followed 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 sta-
tions (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
dashes “----”. This is not to be considered
as an incorrect code entry.
After entering the fourth digit (within 20
seconds), 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 enter 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 maximum
of 24 hours. The waiting time will be
shown on the display with the word
“WAIT”. When this goes off it is possi-
ble to start the new code entry proce-
dure.
Code Card
This the document that certifies posses-
sion of the radio. The Code Card contains
the radio model, serial number and secret
code.
IMPORTANT Keep the Code Card care-
fully to be able to give the related data to
the competent authorities in the event of
theft. PAUSE FUNCTION
To pause the CD player, press button
MUTE. The display will show “PAUSE”.
To resume playing the track, press button
MUTE again.
The pause function is deactivated chang-
ing the sound source.
ANTITHEFT PROTECTION
The radio is fitted with an antitheft pro-
tection system based on the exchange of
information between the radio and the
electronic control unit (Body Computer)
installed on the car.
This system warrants the highest level of
security and prevents entry of the secret
code every time the radio supply is dis-
connected.
If the result of the check is positive, the
set starts working, whereas if the com-
parison 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 ac-
cording to the procedure described in the
following paragraph.
