AUDIO
Service Procedure
SPEED DEPENDENT VOLUME CONTROL
Description
If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises
at higher driving speeds.
The radio receives a speed signal from the vehicle speed sensor (VSS) and selects the output volume.
PERSONAL AUDIO SETTINGS
Description
The radio is designed to store several settings (volume, bass, treble, preset stations and level of speed depen-
dent volume control) with every NATS ignition key used. Up to a maximum of 4 NATS keys can be registered.
During the communication mentioned under “Anti-Theft System”, the radio will recognize the used ignition key
and select the accompanying settings.
Item Service procedure Description
Battery disconnection No additional action required. —
Radio needs repair Repair needs to be done by authorized
representative of radio manufacturer since
radio cannot be operated unless it is reset
to NEW state, using special decoding
equipment.—
Replacement of radio by new part No additional action required. Radio is delivered in NEW state.
Transferring radio to another vehicle/
replacement of radio by an “old” partRadio needs to be reset to NEW state by
authorized representative of radio manu-
facturer.—
Replacement of IMMU Radio needs to be reset to NEW state by
authorized representative of Clarion.After switching on the radio, it will display
“SECURE” after 1 minute.
No communication from IMMU to radio 1. If NATS is malfunctioning, check NATS
system.
2. After NATS is repaired, reset radio to
NEW state by authorized representative
of Clarion.After switching on the radio, the radio will
display “SECURE” after 1 minute. Further
use of radio is impossible until communica-
tion is established again, or after radio is
reset by authorized representative of Clar-
ion.
When initialized between ECM and IMMU. Radio needs to be reset to NEW status by
authorized representative of Clarion.After switching on the radio, it will display
“SECURE” after 1 minute.
