NOTES FOR CD OPERATION
• Do not attempt to take this unit apart or
attempt repairs yourself.
This unit is a very intricate device that uses a laser pickup to
retrieve information from the surface of compact discs. The
laser is carefully shielded so that its rays remain inside the
cabinet. Therefore, never try to disassemble the player or
alter any of its parts since you may be exposed to laser rays
and dangerous voltages.
Laser products:
Wave Length—780 nm
Laser Power—No hazardous radiation is emitted
with safety protection.
■ The top and rear panels of the unit become
warm while a disc Is being played.
This Is one way in which the unit dissipates heat and is not a
malfunction.
■ Handle this unit with care when carrying or
storing, do not subject it to any strong bumps
or impacts.
Always remove the disc before storing the unit for any
period of time.
■ Turn down the volume control.
Compact discs have much less noise and a much wider
dynamic range. Consequently, you may turn the volume up
too high if you adjust it by trying to listen to surface noise as
you might with a phonograph record. To prevent this prob­
lem, turn the volume down, raising it as desired only after
the music has started playing.
■ Time displayed by this unit may differ slightly
from the track time in the disc liner note.
The liner note included with each compact disc lists the
playing times of each track. Since the times calculated by
this unit include pause intervals, the displayed time may
differ from the liner note time by this amount.
■ Do not place this unit near a tuner or tele­
vision.
This unit uses high frequency signals and can cause
interference with other radio and television reception. If this
occurs, move this unit further away from the radio or
television or change from an interior to an exterior television
antenna.
CONCERNING COMPACT DISCS
Observe the following precautions to enjoy the same out­
standing 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 remov­
ing discs from their cases.
•Do not bend the disc.
•Do not use record cleaning sprays or static electricity
prevention 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.
•When wiping discs, always move the cloth directly outward
from the center of the disc, not in a circular motion as with
standard phonograph records.

(In compact discs, circular scratches along a line of pits
are more likely to cause errors than straight scratches
across many lines of pits.)
•If the disc is brought from a cold environment into a warm
room, dew may form on the disc. Wipe this off with a soft,
dry cloth before using the disc.
• Do not try to dry discs with a hair dryer.
• Do not write on the labei side with a bail-point pen, hard
pencil or other writing utensil.
■ 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. Locations with high humidity or a lot of dust
3. Locations directly exposed to a heat outlet or heating
appliance
4. in the glove compartment or rear ledge of an auto­
