NOTES REGARDING COMPACT DISC PLAYER REPAIRS
(1) Preparations
1)Compact disc players incorporate agreat many ICS as well
as the pickup (laser diode). These components are
sensitive to ,and easily affected by ,static electricity. If
such static electricity is high voltage, components can be
damaged, and for that reason components should be
handled with care.
2) The pickup is composed of many optical components and
other high-precision components. Care must be taken,
therefore, to avoid repair or storage where the temperature
of humidity is high, where strong magnetism is present, or
where there is excessive dust.
(2)Notes for repair
1) Before replacing acomponent part, first disconnect the
power supply lead wire from the unit.
2) AH equipment, measuring instruments and tools must be
grounded.
3) The workbench should be covered with aconductive sheet
and grounded.
When removing the laser pickup from its conductive bag,
do not place the pickup on the bag. (This is because there
is the possibility of damage by static electricity.)
4) To prevent AC leakage, the metal part of the soldering iron
should be grounded.
5) In removing short circuit solder of LASER PICKUP, use
ceramic heater type of soldering iron.
6) Workers should be grounded by aearth band (1MQ).
7) Care should be taken not to permit the laser pickup to
come in contact with clothing, in order to prevent static
electricity changes in the clothing to escape from the
earth band.
8) The laser bea mfrOm the Dicku~ should NEVER be
directly facing the eves orbares kin.

NOTES REGARDING HANDLING OF THE PICKUP
(1) Notes for transport and storage
1)
2)
3)
In retaining the product, high temperature, high humidity
and dusty circumstances must be avoided. After taking it
out of packing box, never leave it at the place where dust
can occur. (Take every possible preventive means
against dust. )
The pickup should always be left in its conductive bag
until immediately prior to use.
As this is minutely adjusted, be careful never give it any
shock from drop or careless handling.
Storage in conductive bag Drop impact
(2) Repair notes
1)The pickup incorporates astrong magnet, and so should
never be brought close to magnetic materials.

NOTES REGARDING HANDLING OF THE
2) The pickup should always be handled correctly and
carefully, taking care to avoid external pressuer and
impact. If it is subjected to strong pressure or impact, the
result may be an operational malfunction and/or damage
to the printed circuit boaed.
\
How to hold the pickup
Grabbina Drint circuit boa rd or DUIling
co nnectina wire causes function
deterioration or failure. Be sure to hold
the whole hous ins.
3) If LASER PICKUP or MECHA ASSY is set or reset with
power supplied. LASER DIODE or PHOTO DETECTOR
is damaged. Be sure to turn off power supply switch
before setting or resetting LASER PICKUP or MECHA
ASSY.
4) To prevent LASER DIODE or PHOTO DETECTOR from
being deteriorated or damaged by static electricity, be
sure to thoroughly practice earthing as apreventive
means against damage from static electricity.
5) Take every possible means against damage of LASER
DIODE or PHOTO DETECTOR from overcurrent or
overvoltage. (Example--Use power source equipped with
current limiter. )
6) If fingerprint or any other foreign material is attached on
objective lens, the function is extremely deteriorated. Be
sure never to touch objective lens. Particularly, be very
careful in removing or fitting lens cover.
PICKUP
7) PICKUP is asingle part, and very minutely adjusted as
such. Therefore, never touch anv of adjustment DO
fixina screws or Drint circuit bints.
oard of PICKUP.
(1) If you touch partially fixed volume soldered on circuit
board (beam quantity adjusting volume), emitted
beam quantity (RF LEVEL) can change. Never touch
partially fixed volume.
(2) If there occurs even avery small shift in the circuit
board fixture position, the function greatly changes. In
handling LASER PICKUP, be very careful to hold
metal part of housing (HOUSING).
8) If metal part of adjusting rod or driver touches circuit
board when power is supplied, it can cause failure. Be
careful.
9) Laser beam may damage the eyes!
Absolutely never permit laser beams to enter the eyes!
Also NEVER switch ON the power to the laser output
part (lens, etc.) of the pickup if it is damaged.
LaserBeam
~+
NEVER look directly at the
laser beam, and don’t let
contact fingers or other
exposed skin.
o
1o)
11)
Cleaning the lens surface
If there is dust on the lens surface, the dust should be
cleaned away by using an air brush (such as used for
camera lens). The lens is held by adelicate spring.
Never attempt to disassemble the pickup.
