2. Place the parts and wiring back in their original positions after replacement or
re-wiring. For proper circuit construction, use of insulation tubes, bonding, gaps to
PCB, etc, is involved. The wiring 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 during repair, the legal responsibility shall be
with the repairing 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 repairing
company.
4. Caution in removal and making wiring connection to the parts for the automobile.
Disconnect the battery terminal after turning the ignition 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 repairing company.
5. Cautions regarding chips.
Do not reuse removed chips even when no abnormality is observed in their
appearance. Always replace them with new ones. (The chip parts include resistors,
capacitors, diodes, transistors, etc). The negative 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 PCB
Before working with a soldering iron, make sure that the iron tip temperature is
around 270... Take care not to apply the iron tip repeatedly(more than three times)
to the same patterns. Also take care not to apply the tip with force.
7. Turn the unit OFF during disassembly and parts replacement. Recheck all work
before you apply power to the unit.
To engineers in charge of repair or inspection of
our products.
Before repair or inspection, make sure to follow 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 equivalent characteristics when replacing them. The use of unspecified
parts shall be regarded as remodeling 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.
