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 SHORT CIRCUITS UNTIL YOU HAVE FINISHED FITTING THE PICK-UP.
Caution:
Laser diodes are extremely susceptible to damage from static electricity. Even if a static discharge does not ruin
the diode, it can shorten its life or cause it to work improperly. When replacing the pick-up, use a conductive mat, a
grounded soldering iron, and so on, to protect the laser diode from static damage.
