2. 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).
2.1. Handling of traverse deck (optical pickup)
1. Do not subject the traverse deck (optical pickup) to static electricity as
it is extremely sensitive to electrical shock.
2. To prevent the breakdown of the laser diode, an anti-static shorting
pin is inserted into the flexible board (FFC board). When removing or
connecting the shorting pin, finish the job in as short time as possible.
Refer to Fig. 2-1.
3. Take care not to apply excessive stress to the flexible board (FFC
board).
4. Do not turn the variable resistor (laser power adjustment). It has
already been adjusted.
Fig. 2-1.

2.2. Grounding for electrostatic breakdown prevention
2.2.1. Human body grounding
Use the anti-static wrist strap to discharge the static electricity from your body. Refer to Fig. 2-2.
Fig. 2-2.
2.2.2. 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. Refer to Fig. 2-3.
Fig. 2-3.
Caution:
The static electricity of your clothes will not be grounded through the
wrist strap.
So take care not to let your clothes touch the traverse deck (optical
pickup).

7. Self-Diagnostic Function
The self-diagnostic feature automatically diagnoses the unit’s mechanism and provides error
information display. It includes self-diagnostic functions for the servo system and mechanism control
switches.
7.1. Servo system self-diagnosis
1. With the test disc (SZZP1054C) loaded, turn off the unit.
2. While pressing and holding the Stop, Pause and Play button, turn on
the unit again. Refer to Fig. 7-1. (The self-diagnostic function is
activated.)
3. The display will show an error code, if any. Refer to Table 7-1.
4. Press the Play button to play the test disc. Refer to Fig. 7-1.
5. The display shows servo system status. Refer to Fig. 7-2. and Table 7-
2.
6. Turn off the unit to exit the self-diagnostic function.
Fig. 7-1.
