CAUTIONS REGARDING HANDLING
CD lens cleaner
The player's pickup lens should not become dirty in normal
use, but if for some reason it should malfunction due to
soiling, contact your nearest PIONEER authorized service
center. Lens cleaners for CD players are commercially
available, but special care should be exercised in their use
since some may cause damage to the lens.
Condensation
When this unit is brought into a warm room from previously
cold surroundings or when the room temperature rises
sharply, condensation may form inside, and the unit may
not be able to attain its full performance. In cases like this,
allow the unit to stand for about an hour or raise the room
temperature gradually.
Cleaning and handling compact discs
÷ The presence of fingerprints or smudges on the surface
of the disc will not directly affect the recorded signals,
but depending on the degree of contamination, the
brightness of the light reflected from the signal surfaces
may be reduced, causing degradation of sound quality.
Always keep your discs clean by wiping them gently
with a soft cloth from the inner edge toward the outer
periphery.
÷ If a disc becomes very dirty, dip a soft cloth in water, and
after wringing it out well, wipe the dirt away gently, and
then remove any water drops with another soft, dry cloth.
÷ Do not use record cleaning sprays or anti-static agents on
discs. Also, never clean discs with benzene, thinner, or
other volatile solvents, since damage to the disc surface
may result.
÷ With this player, use discs which display the mark shown
below. (Optical audio digital discs.)
÷ When holding discs, do not touch their signal surfaces.
Hold by the edges, or by one edge and the center hole.
÷ Do not affix gummed labels or tape to the label surfaces.
Also, do not scratch or damage the label.
÷ Discs rotate at high speed inside the player. Do not use
damaged (cracked or warped) discs.

POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the plug by
tugging the cord and never touch the power cord when your hands
are wet as this could cause a short circuit or electric shock. Do not
place the unit, a piece of furniture, etc., on the power cord, or pinch
the cord. Never make a knot in the cord or tie it with other cords.
The power cords should be routed such that they are not likely to
be stepped on. A damaged power cord can cause a fire or give you
an electrical shock. Check the power cord once in a while. When
you find it damaged, ask your nearest PIONEER authorized service
center or your dealer for a replacement.
Location
Install the player in a well-ventilated location where it
will not be exposed to high temperatures or humidity.
Do not install the player in a location which is exposed to
direct rays of the sun, or near stoves or radiators. Excessive
heat can adversely affect the cabinet and internal
components. Installation of the player in a damp or dusty
environment may aiso result in a malfunction or accident.
(Avoid installation near cookers etc., where the player may
be exposed to oily smoke, steam or heat.)
Precautions regarding installation
÷ Placing and using the compact disc player for long periods
on heat-generating sources such as amplifiers or near
spotlights, etc. will affect performance. Avoid placing the
player on heat-generating sources.
÷ Install this compact disc player as far as possible from
tuners and TV sets. A compact disc player installed in
close proximity to such equipment, may cause noise or
degradation of the picture.
÷ Such noise may be particularly noticeable when an indoor
antenna is used. In such cases, make use of an outdoor
antenna, or turn off power to the compact disc player.
÷ When the unit is used in a loud-sound environment, for
example near a speaker, sound skip may occur. In such a
case, install the unit apart from the speaker or reduce the
listening volume.
÷ Please place this unit on a level surface and a stable
flatform.
÷ Besure that the player, including its audio and power
supply cords, dose not touch vibrating materials.
This player has a shock absorber incorporated in the
insulators to absorb vibration. Any other cause of vibration,
other than the insulators, may cause the disc to skip.

Cleaning the player
To clean the PLAYER wipe with a soft, dry cloth. For stubborn
dirt, moisten a soft cloth with a weak solution of neutral
detergent (diluted in five to six parts water), wring the cloth
well, and wipe away the dirt. Also use a dry cloth to wipe
the surface dry. Do not use volatile liquids such as benzene
and thinner which are harmful to the unit.
Storing discs
÷ Discs are made of the same kinds of plastic used for con-
ventional analog audio records. Be careful not to allow discs
to warp; always store discs in their cases vertically, avoid-
ing locations with high heat or humidity, or extremely low
temperatures. Avoid leaving discs in cars, since the seat of
a car in direct sunlight can become unbelievably hot.
÷ Always read and abide by the precautionary notes listed
on disc labels.
