PRECAUTIONS WHEN CHANGING LASER PICK-UP
When removing the pick-up assembly, short circuit the PCB tracks on the optical block as show in
the drawing in order to protect the pick-up before removal.
NOTE : Replacement pick-up assemblies are supplied with the PCB pattern already protected.
DO NOT REMOVE THE SHOR T CIRCUITS UNTILYOU HA VE FINISHED FITTING THE PICK-
UP.

Caution:
Laser diodes are extremely susceptible to damage from static electricity. Even if a static dis-
charge does not ruin the diode, it can shorten its life or cause it to work improperly. When replac-
ing the pick-up, use a conductive mat, a grounded soldering iron, and so on, to protect the laser
diode from static damage.
