1.3 Precautions for Service

1.3.1 Handling of Traverse Unit and Laser Pickup
(1) Do not touch any peripheral element of the pickup or the actuator.

2) The traverse unit and the pickup are precision devices and therefore must not be subjected to strong shock.

3) Do not use a tester to examine the laser diode. (The diode can easily be destroyed by the internal power supply of the tester.)

4) To replace the traverse unit, pull out the metal short pin for protection from charging.

5) When replacing the pickup, after mounting a new pickup, remove the solder on the short land which is provided at the center of
the flexible wire to open the circuit.

(6) Half-fixed resistors for laser power adjustment are adjusted in pairs at shipment to match the characteristics of the optical block.

Do not change the setting of these half-fixed resistors for laser power adjustment.

1.3.2 Destruction of Traverse Unit and Laser Pickup by Static Electricity
Laser diodes are easily destroyed by static electricity charged on clothingor the human body. Before repairing peripheral elements of
the traverse unit or pickup, be sure to take the following electrostatic protection:
(1) Wear an antistatic wrist wrap.
(2) With a conductive sheet or a steel plate on the workbench on which the traverse unit or the pick up is to be repaired, ground the
sheet or the plate.
(3) It solders to two short circuit sections on the substrate of a pick-up.
(4) After removing the flexible wire from the connector (CN101), short-circuit the flexible wire by the metal clip.
(5) Short-circuit the laser diode by soldering the land which is provided at the center of the flexible wire for the pickup.
After completing the repair, remove the solder to open the circuit.
