The auto radio is ensuring
the following functions:
- radio listening ( on FM four geographical areas may be programmed)
- displaying of the station name in RDS on the best transmitter ( AF function).
- receiving of traffic information ( TA function )
- receiving of short information and emergency announcements ( PTY NEWS).
Radio function - on FM four geographical areas may be programmed
The radio receiver is using three selection modes that may be seen on the screen and approached
on the radio front side: - manually ( MANU )
- by pre-selection (PRESET )
- in alphabetical order (LIST)
Ca ssettes player
This function is completely automatic, immediately the source has been selected.
NOTE : only Dolby and both direction unwinding, with t he bl ank searching( empty
spaces), are approachable by means of specific keys.
OBSERVATION : function MUTE by vocal synthesis or telephone, is stopping the cassette
playing.
Thermal protection
If the ra dio temperature is too high for an opt imal operation, the volume is automatically
reduced ( without modification of the volume on the display ).

C ode protection
T he radio is protected by means of a four digit code. This code is introduced by the
radio keys at each battery disconnection.
Co de introduction by means of the radio keys : in order to valid one digit introduction,
push the next key ( see the operation technical book).
In case of a wrong code, the instrument is getting blocked ( one minute for the first error, two
minutes for the second error, four minutes for the third…)
Af ter first code introduction, some confi gurations must be programmed ( see chapter”
configuration”). These are remaining programmed till battery disconnection.
NOTE : the return to the “wave jammer” mode is possible by simultaneously push-
ing of the keys 2 and 5, putting the radio under tension. Wait then for two minutes.
Programming
OBSERVATION : in order to select the radio operation are a, push simultaneously keys 2
and 5, putting the radio under tension. Wait then for about two minutes. Introduce the four digits
code, then:

RADIO
“ Expert “ operati on mode.
In order to pass in configuration ( Expert
mode), perform a long pushing (4 sec) on “ source”
key until a beep is heard. This is allowing the following functions adjustment:
- AF mode activation ( automatic resetting)
- Volume m odification subject to t he vehicle speed ( 5 for maximal m odification, 0 for
modification canceling) - Loudness mode activation
- Assisted radio receiver mode a ctivation
- Number of speakers activation ( 2 or 4)
- Manual or dynamic list selection
NOTE : during configuration, one impulse on “source” key, is canceling the modifications.
Volume
The volume may be settled subject to vehicle speed. For the activation of this function, select
the desired volume modification curve, by means of the “ Expert “ mode ( push longer on the
“source” button, until a beep is heard): 5 for maximal modification, 0 for modification canceling.
OBSERVATION : the auto radio is provided with a sound tonality modification subject to
vehicle type. To modify that, see chapter “ configuration”.
Self-diagnostic
This mode is allowing some main functions controlling :
- speakers testing
by simultaneously pushing of 2 and 4 keys, the speakers are supplied one by one. The display is
enabling their location. - reception level testing ( afte r fr equency displaying)
by simultaneously pushing of 1 and 6 keys, the display is showing the radio reception criteria:
- 9 or letter = good reception
- 3 = defective signal
- 2 = stereo sound loosing
Keys testing
The introduction of this mode is performed by simultaneously pushing of 3 and ON/OFF
keys. Each key pushing may be seen on display. The exit from this checking mode is automatic,
after all keys have been pushed. GENERAL
