2 Handling Precautions for Traverse Deck
TOP PREVIOUS NEXT
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)
2.2 Grounding for electrostatic breakdown prevention
2.2.1 Human body grounding

2.1 Handling of traverse deck (optical pickup)
TOP PREVIOUS NEXT
1. Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock.
2. To protect the laser diode against electrostatic breakdown, short the flexible board (FFC board) with a clip or similar object. 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. Refer to
Fig. 2-1.
Fig. 2-1.

2.2.2 Work table grounding
TOP PREVIOUS NEXT
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).

6 Error Code Display and Servo Adjustment Function
TOP PREVIOUS NEXT
This unit has an error code display function, so that if the unit operates incorrectly, the fault is displayed using an error code on the FL display of the Tuner/Amplifier (SA-EH570). It also has a servo adjustment function for displayingthe status of servo system functions (Focus, Tracking, CLV servo) on the FL display of the Tuner/Amplifier. The system control IC and FL display are part of the Tuner/Amplifier so make sure the system has been connected properly beforeusing these functions. Use these two functions for guidance during fault diagnosis and repair.
Note:
Check beforehand for scratching or soiling of the test disc (SZZP1054C), and soiling or other problems with the pickup lens.
6.1 Error code display procedure
6.1.1 Automatic adjustment results
6.1.2 Checking the mechanism switches
6.2 Servo adjustment procedure
6.3 Error code based on troubleshooting
