1. Note
Refer to the service manual for Model No. SA-DT100/SA-DT300 (Order No. AD0205102C8) for
information on Accessories and Packaging.
2. Handling Precautions for Traverse Deck
The laser diode in the optical pick-up 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 optical pick-up.
2.1. Handling of optical pick-up
1. Do not subject the optical pick-up to static electricity as it is
extremely sensitive to electrical shock.
2. To prevent the breakdown of the laser diode, an antistatic shorting
pin or similar object is inserted into the flexible board (FFC board).
Refer to
Fig. 2-1.
finish the job in as short time as possible.
3. Be careful not to apply excessive stress to the flexible board (FFC
board).
4. Do not turn the variable resistor (Laser power adjustment).
2.2. Grounding for electrostatic breakdown prevention
2.2.1. Human body grounding
Use the antistatic wrist strap to discharge the static electricity from your body. Refer to
/ When removing or connecting the shortpin,
