2) Short the laser diode protection circuit on the PICK UP

BLOCK’s flexible cable with solder as shown.

Caution

To protect the laser diode from damage caused by high voltage

static electricity, a laser diode protection circuit has to be

shorted before disconnecting the flexible cable (P200

connector on the MECHANISM PCB). It is recommended that

you put solder on the top of the soldering iron as shown in Fig.

3-5 then short the circuit at once. When you replace the

TRAVERSE MECHA., be sure to connect the P200 connector

before removing the solder at the shorted parts.
