Additional information10

Do not place objects on this unit

Do not place any objects on top of this unit.

Do not obstruct the ventilation holes.

Do not use this unit on shaggy rugs, beds, sofas, etc., or

wrapped in cloth, etc. Doing so will prevent the heat from

dispersing, leading to damage.

Do not expose to heat.

Do not place this unit on top of an amplifier or other

component that generates heat. When rack mounting it, to

avoid the heat given off by the amplifier or other audio

component, place it on a shelf below the amplifier.

• Turn off the unit’s power when not using it.

• Depending on signal conditions, striped patterns may

appear on a TV screen and noise may enter the sound of

radio broadcasts when the unit’s power is on. If this

happens, turn the unit’s power off.

About condensation

If this unit is moved suddenly from a cold place into a warm

room (in winter, for example) or if the temperature in the room

in which this unit is installed rises suddenly due to heater

operation, etc., water droplets (condensation) may form

inside (on operating parts and the lens). When condensation

is present, this unit will not operate properly and playback is

not possible. Let this unit stand at room temperature for 1 or

2 hours with the power turned on (the time depends on the

extent of condensation). The water droplets will dissipate and

playback will become possible. Condensation can also occur

in the summer if this unit is directly exposed to the air flow

from an air-conditioner. If this happens, move this unit to a

different place.

Cleaning the product

• Unplug the power cord from the power outlet when

cleaning this unit.

• Clean this unit using a soft cloth. For tough dirt, apply

some neutral detergent diluted in 5 to 6 parts water to a

soft cloth, wring out thoroughly, wipe off the dirt, then

wipe again with a soft, dry cloth.

• Alcohol, thinner, benzene, insecticides, etc., could cause

the print or paint to peel off. Also, leaving rubber or vinyl

products in contact with this unit for long periods of time

could mar the cabinet.

• When using chemical-impregnated wipes, etc., read the

cautions included with the wipes carefully.

Cleaning the lens

• This unit’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 outside. 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 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 unit. Do not attempt to play such

discs, as they could damage this unit.
