Note:Note on repairing the Base Unit Ass’y.
When operating or repairing the unit, grounding is required to pre-
vent damage caused by static electricity and is as follows:
1. Grounding for the human body
Besure to wear a wrist-strap for grounding (with impedance lower
than 10
8
Ω
) whose other end is ground. The strap works to drain
away the static electricity build-up on the human body.
2. Grounding for the work table
Be sure to lay a conductive sheet (with impedance lower than 10
8
Ω
)
on the table, sure as a sheet of copper, which is ground.
3. As static electricity build-up on clothes does not drain away, be
careful not to let your clothes touch the unit.
