1.2.
Electrical Tests
1. Unplug the power cord and check for continuity between the earth ground connection on the plug and the metal cabinet.
There should be zero ohm resistance found.
2. With the unit unplugged, short the AC Live-Neutral of the plug with a jumper wire.
3. Turn ON the power switch.
4. Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metal cabinet part, such
3. Turn ON the power switch.
4. Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metal cabinet part, such
as screwheads, etc.
Note
Note
Some exposed parts may be isolated from the chassis by design. They read infinity.
5. If the measurement is less than 1 M
Ω, there may be a danger of electric shock.
Note
This hazardous condition must be corrected before the unit is returned to the end user.
1.3.
Standard for Repair Service
Repair service shall be provided in accordance with repair technology information such as service manual so as to prevent fires,
injury or electric shock, which can be caused by improper repair work.
injury or electric shock, which can be caused by improper repair work.
1. When performing repairs, neither the products nor its parts or components shall be modified.
2. If cable assembly is supplied as the smallest unit when servicing, make sure to replace the cable assembly.

1.4.
For Service Technicians
ICs and LSIs are vulnerable to static electricity.
When repairing, the following precautions will help to prevent recurring malfunctions.
When repairing, the following precautions will help to prevent recurring malfunctions.
1. Cover plastic parts with aluminum foil.
2. Ground soldering irons.
3. Use a conductive mat on the worktable.
4. Do not hold IC or LSI pins with bare fingers.
