Mi CONCERNING COMPACT DISCS
Handling precautions
Only compact discs having this mark can
be used with this unit. ) ise
DIGITAL AUDIO
Observe the following precautions to enjoy the same
outstanding sonic performance from your Compact Discs
for many years.
Hold compact discs by the edges so the surface is not soiled
with fingerprints.
© Be careful not to scratch the surface with fingernails or other
sharp objects, particularly when inserting and removing discs
from their cases.
®Do not bend the disc.
Do not use record cleaning sprays or static electricity preven-
tion liquids.
®Do not wipe with benzine, thinner or any other solvent. If the
surface is soiled, wipe gently with a soft, damp (water only)
cloth.
eWhen wiping discs, always move the cloth directly outward
from the center of the disc, not in a circular motion as with
standard phonograph records.
(Incorrect)
(Correct)
(In compact discs, circular scratches along a line of pits are
more likely to cause errors than straight scratches across many
lines of pits.)
*\f the disc is brought from a cold environment into a warm
room, moisture may form on the disc. Wipe this off with a soft,
dry, lint-free cloth before using the disc.
Do not dry discs with a hair dryer.
®Do not write on the label side with a ball-point pen, hard pencil
or other writing utensil.
Handle compact discs with care. Fingerprints, dirt and
scratches can cause skipping and distortion.
Storage precautions
Be sure to store discs in their cases to protect them from dust,
scratches and warping.
*Do not place or-store discs in the following places:
1) Locations exposed to direct sunlight.
2) Humid or dusty locations.
3) Locations directly exposed to a heat outlet or heating
appliance.
4) In the glove compartment or rear ledge of an automobile.

2. Insert the batteries
and close the cover.
Use two UM-4
“AAA” (RO3) size
(1.5V) batteries.
@ To remove the batteries
Reverse procedure above.
Hf Battery life About 1 year.
(Depending on frequency of use.)
@ Notes concerning use of dry
batteries
® Do not use re-chargeable batteries (Ni-Cd
type).
Be sure the batteries are inserted so that
the positive (+) and negative (—) polarities
are correct. Batteries installed with incor-
rect polarities may leak and damage the
remote-control transmitter.
Never subject the batteries to excessive
heat or flame; do not attempt to disas-
semble them; and be sure they are not
short-circuited.
®lf the remote-control transmitter is not to
be used for a long time, remove the
batteries and store them in a cool dark
place.
eAlways remove old, weak or worn-out
batteries promptly and dispose of them.
®Never mix old and new batteries, nor
batteries of different types (carbon or
alkaline).
Although battery life varies depending
on how often the remote-control trans-
mitter is used, the batteries should be
replaced about once every year on the
average.
The batteries should also be replaced if
commands from the remote-control trans-
mitter are not received by this player
even when the transmitter is held close
to the player's front panel.
elf the batteries leak, clean the battery
holder well before inserting new bat-
teries.
@Do not use remote-control transmitter
for TV sets, VCRs or other components
at the same time as this player’s remote-
control transmitter since this would
result in a mistaken operation.
Operation notes
Note that operation may not be correct if direct sunlight or other strong light strikes the remote-control signal receptor part of this unit. If there
is a problem, place the unit away from the direct sunlight or other strong light source.
Face it toward the remote-control
signal receptor.
(Obstacles should
be avoided.)
Use the remote-control transmitter
within 7 meters.
==
7 meters
(23 ft.)
Be sure the transmitter part of the remote-control
transmitter and the receptor part of this unit are free
from dust. Excessive dust might prevent reception.
Avoid dust.
Note: Thecontrol panel of the remote-control transmitter may be covered by a clear plastic protective sheet. This sheet may be removed if

Mi HANDLING PRECAUTIONS FOR OPTICAL PICKUP
The laser diode in the optical pickup may break down due to potential difference caused by static electricity of
clothes or human body.
So, be careful of electrostatic breakdown during repair of the optical pickup.
¢ Handling of optical pickup Bc. Suen login
1. Do not give excessive shock to the optical pickup twee te 4 P|
because it is of extremely precise structure. iS nena ;
2. To prevent the breakdown of the laser diode, an anti-
static shorting pin is inserted into the flexible board.
(FPC board)
When removing or connecting the short pin, finish the
job tn as short time as possible.
3. Take care not to apply excessive stress to the flexible
board. (FPC board)
4. Do not turn the variable resistor (laser power adjust-
ment). It has already been adjusted.
Be sure to short this position
(Use the shorting pin or clip.)
Optical pickup
Lens (Do not touch)
FPC board
(Handle it carefully)
Variable resistor (Do not turn)
® Grounding for electrostatic breakdown prevention
1. Human body grounding
Use the anti-static wrist strap to relieve the static
electricity from your body.
2. Work table grounding
Put a conductive material (sheet) or steel sheet on the
area where the optical pickup ts placed, and ground the Wrist strap
sheet.
(Anti-static
bracelet)
Caution:
The static electricity of your clothes will not be grounded
through the wrist strap. So, take care not to let your
clothes touch the optical pickup.
