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)
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.

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.

Important safety notice:
Components identified by
mark have special characteristics important for safety.
Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. are used.
When replacing any of components, be sure to use only manufacturer’s specified parts shown in the parts list.
The supply part number is described alone in the replacement parts list.
Caution!
IC and LSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair.
Cover the parts boxes made of plastics with aluminum foil.
Ground the soldering iron.
Put a conductive mat on the work table.
Do not touch the legs of IC or LSI with the fingers directly.
