6. Cautions in handing fl exible PWB
Before working with a soldering iron, make sure that the
iron tip temperature is around 270 o C. Take care not to
apply the iron tip repeatedly (more than three times) to
the same patterns. Also take care not to apply the tip
with force.
7. Turn the unit OFF during disassembly and parts replace-
ment.
Recheck all work before you apply power to the unit.
8. Cautions in checking that the optical pickup lights up.
The laser is focused on the disc refl ection surface throu-
gh the lens of the optical pickup. When checking that the
laser optical diode lights up, keep your eyes more than
30cms away from the lens. Prolonged viewing of the la-
ser within 30cms may damage your eyesight.
9. Cautions in handing the optical pickup
The laser diode of the optical pickup can be damaged by
electrostatic charge caused by your clothes and body.
Make sure to avoid electrostatic charges on your clothes
or body, or discharge static electricity before handling
the optical pickup.
9-1. Laser diode
The laser diode terminals are shorted for transporta-
tion in order to prevent electrostatic damage. After re-
placement, open the shorted circuit. When removing
the pickup from the mechanism, short the terminals by
soldering them to prevent this damage.
9-2. Actuator
The actuator has a powerful magnetic circuit. If a ma-
gnetic material is put close to it, its characteristics will
change.
Ensure that no foreign substances enter through the
ventilation slots in the cover.
9-3. Cleaning the lens
Dust on the optical lens affects performance. To clean the
lens, apply a small amount of isopropyl alcohol to lens pa-
per and wipe the lens gently.
