BLOCKÕs 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.
