be damaged by static electricity from your body. Be sure to
take static electricity countermeasures when working around
the optical pickup.
2-4-1 Static Electricity Countermeasure Methods
1. Ground yourself
Use an anti-static wrist strap to discharge static electrici-
ty from your body.
2. Ground the workbench
Lay a conductive material (sheet) or steel sheet on the
surface where the traverse unit (optical pickup) is to be
placed, then ground the sheet.
2-6 Disassembling the Clamper Weight, Clamper
Yoke, Magnet and Clamper
1. Release the tab, and pull out the clamper.
2-4-2 Short-circuit the laser diode
Solder the land in the flexible cable of the optical pickup.
Notes
Y Be sure to do this befer disconnecting the flexible cable
of the optical pickup from the module C.B.A.
Y Use an anti-static soldering iron to short-circuit and
unshort-circuit laser diode.
2. Release the 3 tabs on the clamper.(Recommended soldering iron: Hakko with ESD counter-
measure)
Y After you have finished repairing the laser diode, follow
the correct procedure to remove the solder from the
short-circuit location. (Refer to page5/2. Assembling and
Disassembling the Optical Pickup (Mechanical Parts).)
