The laser diode in the traverse unit (optical pick up) is easy to be destroyed by clothes and the human body
to the electrified static electricity.
Please note the explosion by static electricity when repairing.
In the equipment which uses an optical pick up (laser diode), an optical pick up is destroyed by the static
electricity of the work environment.
Please do the earth processing and work.
2. About the earth processing for the electrostatic destruction prevention
1) Earth of work stand
Please pull the conductive material (conductive sheet) or the iron plate to the depository
place of the traverse unit (optical pick up), and take the earth to ground.
2) Human body earth
Please use the anti-static wrist strap to exhaust the electrified static electricity to the human body.
3. Handling the optical pick up
1) Please return according to a correct procedure based on short processing after exchanging
parts.
2) Do not use a tester to check the condition of the laser diode in the optical pick up .The tester 's internal
power source can easily destroy the laser diode.
4. Attention when unit is disassembled
Please refer to "Disassembling method" for how to detach .
Conductive material (conductive
sheet) or the iron plate
anti-static wrist strap
Attention when MD pickup is exchanged
1. About the static electricity protection measures
Solder short
1) Please be sure to solder before a flexible wire is removed from connector on a main printed
circuit board as shown.
if you removes without soldering.the MD picking up assembly might destroy
2) When installing , solder in the part of short round should be removed after a flexible wire is connected with
connector.
