3. Operating Instructions
4. Handling Precautions for Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to
potential difference caused by static electricity of clothes or human body.
So, be careful of electrostatic breakdown during repair of the traverse deck
(optical pickup).
4.1. Handling the traverse deck (optical pickup)
1. The traverse deck (optical pickup) is an extremely high-precision construction
and must not be subjected to impact, excessive 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 Fig. 1 )
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.
