Note: Note on repairring the Base Unit assy.
When opening 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
Be sure 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
9
Ω
) on the table, such as a sheet of copper, which is ground.
3. As static electricity built-up on clothes does not drain away, be
careful not to let your clothes touch the unit.

4. Do not apply excessive force to the lens when wiping. Optical
device is structured by very sensitive mechanical parts. The lens
holding mechanism may have damage if excessive force is ap-
plied.
