vibration, or other types of rough handling.
2. In order to prevent static electricity damage to the laser diode,
use a short pin or similar tool to short the optical pickup's flexible
circuit boards after they have been disconnected from the main
circuit board. (as shown in
3. Handle the flexible circuit boards with care; excessive force could
cause them to be broken.
4. Do not turn the pre-set variable resistor (for adjustment of the
laser power); it has been adjusted at the factory.
(as shown in
4.2. Grounding for electrostatic breakdown prevention
1. Human body grounding
Use the anti-static wrist strap to discharge the static electricity
from your body. (as shown in
2. Work table grounding
Put a conductive material (sheet) or steel sheet on the area where
the traverse deck (optical pickup) is placed, and ground the sheet.
