Clarion ARX7370R Service Manual

@ To engineers in charge of repair or
inspection of our products.
Before repair or inspection,make sure to fol-
low the instructions so that customers and
Engineers in charge of repair or inspection can
avoid suffering any risk or injury.
1. Use specified parts.
The system uses parts with special safety features
against fire and voltage.Use only parts with equiva-
Jent characteristics when replacing them.
The use of unspecified parts shall be regarded as re-
modeling for which we shall not be liable. The onus of
product liability (PL) shall not be our responsibility in
cases where an accident or failure is as a result of
unspecified parts being used.
2. Place the parts and wiring back in their original posi-
tions after replacement or re-wiring.
For proper circuit construction,use of insulation
tubes,bonding,gaps to PWB,etc,is involved.The wir-
ing connection and routing to the PWB are specially
planned using clamps to keep away from heated and
high voltage parts.Ensure that they are placed back
in their original positions after repair or inspection.
If extended damage is caused due to negligence dur-
ing repair,the legal responsibility shall be with the re-
pairing company.
3. Check for safety after repair.
Check that the screws,parts and wires are put back
securely in their original position after repair.Ensure
for safety reasons there is no possibility of secondary
ploblems around the repaired spots.
If extended damage is caused due to negligence of
repair,the legal responsibility shall be with the repair-
ing company.
4. Caution in removal and making wiring connection to
the parts for the automobile.
Disconnect the battery terminal after turning the igni-
tion key off.If wrong wiring connections are made with
the battery connected, a short circuit and/or fire may
occur.If extensive damage is caused due to negligence
of repair,the legal responsibility shall be with the re-
pairing company.
5. Cautions regarding chips.
Do not reuse removed chips even when no abnormal-
ity is observed in their appearance.Always replace
them with new ones.(The chip parts include
resistors,capacitors, diodes, transistors,etc). The nega-
tive pole of tantalum capacitors is highly susceptible
to heat,so use special care when replacing them and
check the operation afterwards.
6. Cautions in handling flexible PWB
Before working with a soldering iron,make sure that
the iron tip temperature is around 270°C.Take care
not to apply the iron tip repeatedly(more than three
times)}to the same patterns.Also take care not to ap-
ply the tip with force.
7. Turn the unit OFF during disassembly and parts
replacement.Recheck all work before you apply power
to the unit.
