Cautions on use

About condensation

Water droplets (condensation) may form inside the unit (on operating parts and
lenses) in the winter, for example, if the unit is moved from a cold place into a
warm room or if the temperature in the room in which the unit is installed rises
suddenly (through heating, etc.). The unit will not operate properly and will not
be playable with condensation inside. Let the unit stand for 1 to 2 hours at room
temperature (though this time depends on the conditions of the condensation)
without turning on the power. The water droplets will evaporate and the unit will
become playable. Condensation can occur in the summer as well if the unit is
exposed to the direct wind from an air-conditioner, etc. If this happens, move the
unit to a different location.
Cleaning the lens
The player's lens should not become dirty in normal use, but if for some reason it
should malfunction due to dust or dirt, consult your nearest Pioneer authorized
service center. Although lens cleaners for players are commercially available, we
advise against using them since some may damage the lens.

Handling discs

Storing
! Always place discs in their cases and store them vertically, avoiding hot,
humid places, places exposed to direct sunlight and extremely cold places.
! Be sure to read the cautions included with the disc.
Cleaning discs
! Discs may not play if there are fingerprints or dust on them. In this case, use a
cleaning cloth, etc., to gently wipe the disc from the inside towards the out-
side. Do not use dirty cleaning cloths.
! Do not use benzene, thinner or other volatile chemicals. Also do not use
record spray or antistatic agents.
! For tough dirt, apply some water to a soft cloth, wring out thoroughly, wipe off
the dirt, then wipe off the moisture with a dry cloth.
! Do not use damaged (cracked or warped) discs.
! Do not let the signal surface of discs get scratched or dirty.
! Do not place two discs in the disc tray, one on top of the other.
! Do not attach pieces of paper or stickers to discs. Doing so could warp discs,
making it impossible to play them. Also note that rental discs often have
labels attached to them, and the label's glue may have oozed out. Check that
there is no glue around the edges of such labels before using rented discs.
About specially shaped discs
Specially shaped discs (heart-shaped, hexagonal, etc.) cannot be played on this
player. Do not attempt to play such discs, as they could damage the player.
About condensation on discs
Water droplets (condensation) may form on the surface of discs if they are moved
from a cold place (particularly in winter) into a warm room. Discs may not play
normally if there is condensation on them. Carefully wipe the water droplets off
the surface of the disc before loading it.
