■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. REMODELING FOR WHICH

WE SHALL NOT BE LIABLE. THE ONUS OF PRODUCT LIABLITY

(PL) SHALL NOT BE OUR RESPONSIBILITY IN CASES WHERE

AN ACCIDENT OR FAILURE IS AS A RESULT OF UNSPECIFIED

PARTS BEING USED OR DUE TO NEGLIGENCE DURING

REPAIR.

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.

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 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 INSPECTION.

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 PROBLEMS AROUND THE REPAIRED SPOTS.

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.

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 HECK 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 ℃. 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.
