Repair or Inspection of our
products:

Before repair orinspection, make sureto
follow the instructionsso that customersand
Engineers in chargeof repair orinspection
can avoid sufferingAny riskorinjury.

1. Use specified parts.
The system uses partswithspecialsafetyfeatures
against Fire and voltage.Useonlypartswithequivalent
characteristics when replacing hem. The use of
unspecified parts shall beregardedasremodelingfor
which we shall notbeliable. The onus of product
liability (PL) shall notbeourresponsibilityincases
where an accident orfailureisasaresultofunspecified
parts being used.

2. Place the partsandwiringbackintheiroriginal
positions after replacement orre-wiring.

For proper circuit construction,useofinsulationtubes,
bonding, gaps to PWB,etc,isinvolved.Thewiring
connection and routing tothePWBarespecially
planned using clamps tokeepawayfromheatedand
high voltage parts. Ensurethattheyareplacedbackin
their original positions afterrepairorinspection.
If extended damage iscausedduetonegligenceduring
repair, the legal responsibilityshallbewiththerepairing
company.

3. Check for safetyafterrepair.
Check that the screws,partsandwiresareputback
securely in their originalpositionafterrepair.Ensurefor

safety reasons there isnopossibilityofsecondary
p oblems around therepairedspots. If extended

r
damage is caused duetonegligenceofrepair,thelegal
responsibility shall be withtherepairingcompany.

4. Caution in removalandmakingwiringconnectiontothe
parts for the automobile.
Disconnect the battery terminalafterturningtheignition
key off. If wrongwiringconnectionsaremadewiththe
battery connected, a shortcircuitand/orfiremayoccur.
If extensive damage iscausedduetonegligenceof
repair, the legal responsibilityshallbewiththerepairing
company.

5. Cautions in soldering
Please do not spreadliquidfluxinsoldering.
Please do not washthesolderingpointaftersoldering.

6. Cautions in solderingforchipcapacitors

Please solder the chipcapacitorsafterpre-heatingfor
replacement because they areveryweaktoheat.
Please do not heatthechipcapacitorswithasoldering
iron
directly.

7. Cautions in handlingforchipparts.

Do not reuse removedchipsevenwhennoabnormality
is observed in theirappearance.Alwaysreplacethem
with new ones. (Thechippartsincluderesistors,
capacitors, diodes, transistors,etc).
Please make an operationtestafterreplacement.

8. Cautions in handlingflexiblePWB
Before working with asolderingiron,makesurethatthe
iron tip temperature isaround270.Takecarenotto
apply the iron tiprepeatedly(morethanthreetimes)to
the same patterns. Also
take care not toapplythetipwithforce.

9. Turn the unitOFFduringdisassemblyandparts
replacement.
Recheck all work beforeyouapplypowertotheunit.
