2) Ruler 30 cm (11.8 in) long
3) Drawing pen
4) Heat gun
5) Alcohol
6) Cloth

REPAIRING PROCEDURENJEL0078S021. Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
2. Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive sil-
ver composition on break with drawing pen. Slightly overlap
existing heat wire on both sides [preferably 5 mm (0.20 in)] of
the break.
SEL012D
4. After repair has been completed, check repaired wire for con-
tinuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
SEL013D
5. Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area
and hot air outlet. If a heat gun is not available, let the repaired
area dry for 24 hours.

NATS AUDIO LINKNJEL0497S12DescriptionNJEL0497S1201The link with the NATS IMMU implies that the audio unit can basically only beoperated if connected to the
matching NATS IMMU to which the audio unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted theft of the audio unit is basically
useless since special equipment is required to reset the audio unit.
Initialization process for audio units that are linked to the NATS IMMU
Perform initialization with CONSULT-II
For initialization, refer to “CONSULT-II operation manual NATS”.
Normal operation
Each time the audio unit is switched on afterwards, the audio unit code willbe verified between the audio unit
and the NATS before the audio unit becomes operational.
When the radio is locked
When NATS link problems occur “SECURE” message will be displayed in three ways indicating three differ-
ent NATS link problems.
“Secure” on a red background indicates that there is a problem in the link between Navi control unit and Audio,
suggesting that there is either a Navigation system fault or the Navi control unit has previously been fitted in
another vehicle.
“Secure” on a green background indicates that there is a problem in the linkbetween NATS IMMU and Audio,
suggesting that there is an audio fault or the audio unit has previously been fitted in another vehicle.
“Secure” on a yellow background indicates that the transponder (NATS key)is not working correctly or it has
previously been fitted in another vehicle.
When a “Secure” message (of any type) is displayed, it can be cleared by re-initializing the NATS system using
CONSULT-II and the associated Immobilizer PIN code (there is no need to return the audio to a Clarion ser-
vice centre). If re-initializing fails to clear a “Secure” message then the component (identified by background
color) is faulty and should be replaced.
NOTE:
When the “Secure” is displayed on VFD display or audio unit, the communication of IMMU and radio, radio
unit or transponder has problem.
Service ProcedureNJEL0497S1202
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 by using CON-
SULT-II and the associated Immobi PIN
code (there is no need to return the audio
or Navi units to a Clarion service centre).—
Replacement of IMMU The communication between IMMU and
radio need to be reset by using CON-
SULT-II and the associated Immobi PIN
code.After switching on the radio, it will display
“SECURE” on a green background.
No communication from IMMU to radio 1. If NATS is malfunctioning, check NATS
system.
2. After NATS is repaired, reset radio to
“Secure” on a green background state
by using CONSULT-II and the associ-
ated Immobilizer PIN code (there is no
need to return the audio to a Clarion
service centre).After switching on the radio, the display
unit will display “SECURE” on a green
background. Further use of radio is
impossible until communication is estab-
lished again, or after radio is reset by
using CONSULT-II and the associated
Immobilizer PIN code (there is no need to
return the audio to a Clarion service cen-
tre).

SPEED DEPENDENT VOLUME CONTROLNJEL0497S13DescriptionNJEL0497S1301If 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 combination meter and selects the output volume.
PERSONAL AUDIO SETTINGSNJEL0497S14DescriptionNJEL0497S1401The radio is designed to store several settings (volume, bass, treble, preset stations and level of speed
dependent volume control) with every NATS ignition key used. Up to a maximum of 4 NATS keys can be reg-
istered. During the communication mentioned under “Anti-Theft System”,the radio will recognize the used
ignition key and select the accompanying settings.
