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.

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.

● 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.

Notes:

● 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 manufactures specified parts shown in the
parts list.

● The marking [RTL] indicates that Retention Time is Limited for this item. After the

discontinuation of this assembly in production, the item will continue to be available for a specific
period of time. The retention period of availability is dependenton the type of assembly, and in
accordance with the laws governing part and product retention. After the end of this period, the
assembly will no longer be available.

● All parts are supplied by MESA.
