CAUTIONS
If it is very cold inside the car and the CD
player is used a little after turning the heater
on, a film of damp may form on the Com-
pact Disc or on the player optics and the
sound may not be perfect. In this case do
not use the CD player for at least an hour,
so that the condensation dissolves natural-
ly and normal operation is resumed.
Driving on rough roads with heavy vibra-
tions may cause skipping when the CD play-
er is working.
PROTECTION AGAINST THEFT
The radio is fitted with an antitheft pro-
tection 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 high-
est level of security and prevents entry of
the secret code every time the radio sup-
ply is disconnected.
After every re-connection an automatic
check procedure is performed during which
the display shows the wording “
CAN-
CHECK ” for about one second. If the result
of the check is positive, the set starts work-
ing, whereas if the comparison codes are
not the same or if the radio is connected for
the first time to the vehicle electric system,
the device informs the user of the need to
enter the secret code according to the pro-
cedure described in the following paragraph.
During the code entry procedure the dis-
play shows the word “ CODE ”. The set will
not work until the correct code is entered
This way the protection system makes the
radio unusable after removal from the dash-
board in the case of theft.
On multimedia CDs in addi-
tion to sound tracks also
data tracks are recorded. Playing
one of these CDs may cause rustling
and such a volume as to compro-
mise road safety, as well as caus-
ing damage to the final stages and
speakers.
