essary for removing it.
*
We cannot supply PWB with component parts in prin-
ciple. When a circuit on PWB has failure, please repair it
by component parts base. Parts which are not mentioned
in service manual are not supplied.

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.
2. Place the parts and wiring back in their original positions after
replacement or re-wiring.
For proper circuit construction, use of insulation tubes, bond-
ing, gaps to PWB, 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 inspec-
tion.
If extended damage is caused due to negligence during re-
pair, the legal responsibility shall be with the repairing com-
pany.
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 re-
paired 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 con-
nected, a short circuit and/or fire may occur. If extensive dam-
age is caused due to negligence of repair, the legal responsi-
bility shall be with the repairing company.
5. Cautions in soldering
Please do not spread liquid flux in soldering.
Please do not wash the soldering point after soldering.
6. Cautions in soldering for chip capacitors
Please solder the chip capacitors after pre-heating for replace-
ment because they are very weak to heat.
Please do not heat the chip capacitors with a soldering iron
directly.
7. Cautions in handling for chip parts.
Do not reuse removed chips even when no abnormality is ob-
served in their appearance. Always replace them with new
ones. (The chip parts include resistors, capacitors, diodes, tran-
sistors, etc).
Please make an operation test after replacement.
8. Cautions in handling flexible PWB
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.
9. Turn the unit OFF during disassembly and parts replacement.
Recheck all work before you apply power to the unit.
