remove the short circuit accordingto the correct procedure. (See this
Technical Guide.)
2. Do not use a tester to check the laser diode for the optical pickup.
Failure to do so will damage the laser diode due to the power supply in
the tester.
5.2. Handling Precautions for Traverse Unit (Optical Pickup)
1. Do not give a considerable shock to the traverse unit (optical pickup)
as it has an extremely high-precise structure.
2. When replacing the optical pickup, install the flexible cable and cut its
short land with a nipper. See the optical pickup replacement procedure
in this Technical Guide. Before replacing the traverse unit, remove the
short pin for preventingstatic electricity and install a new unit. Connect
the connector as short times as possible.
3. The flexible cable may be cut off if an excessive force is applied to it.
Use caution when handling the cable.
4. The half-fixed resistor for laser power adjustment cannot be adjusted.
Do not turn the resistor.
