Precautions

On placement
 At high volume, over long periods of time,

the cabinet becomes hot. This is not a

malfunction. However, touching the

cabinet should be avoided. Do not place the

system in a confined space where

ventilation is poor as this may cause

overheating.

 Do not install the system near heat sources

such as radiators or air ducts, or in a place

subject to direct sunlight, excessive dust,

mechanical vibration, or shock.

 Do not install the system in an inclined

position. It is designed to be operated in a

horizontal position only.

 Do not place heavy objects on the system.
On operation
 If the system is brought directly from a cold

to a warm location, or is placed in a very

damp room, moisture may condense on the

lenses inside the unit. Should this occur,

the system may not operate properly. In

this case, remove the disc and leave the

system turned on for about half an hour

until the moisture evaporates.

 If anything falls into the cabinet, unplug

the unit and have it checked by qualified

personnel before operating it any further.

On cleaning

Clean the cabinet, panel, and controls with a

soft cloth slightly moistened with a mild

detergent solution. Do not use any type of

abrasive pad, scouring powder, or solvent

such as alcohol or benzine.

If you have any questions or problems

concerning your system, please consult your

nearest Sony dealer.
On cleaning discs, disc/lens cleaners

Do not use cleaning discs or disc/lens

cleaners (including wet or spray types). These

may cause the apparatus to malfunction.
On your TV’s color

IMPORTANT NOTICE

Caution: If you leave the same image (a

still video image, an on-screen display

image, etc.) displayed on your TV for an

extended period of time, you risk

permanent damage to your television

screen. Projection televisions are

especially susceptible to this.

On moving the system

Before moving the system, make sure that

there is no disc inserted, and remove the AC

power cord from the wall outlet.
On handling discs
 To keep the disc clean, handle the disc by

its edge. Do not touch the surface.

 Do not attach paper or tape to the disc.

 Do not expose the disc to direct sunlight or

heat sources such as hot air ducts, or leave

it in a car parked in direct sunlight as the

temperature may rise considerably inside

the car.

On cleaning discs
 Before playing, clean the disc with a

cleaning cloth.

Wipe the disc from the center outward to

the edge.

 Do not use solvents such as benzine,

thinner, commercially available cleaners, or

anti-static spray intended for vinyl LPs.

This system can only play back a standard

circular disc. Using neither standard nor

circular discs (e.g., card, heart, or star shape)

may cause a malfunction.

Do not use a disc that has a commercially

available accessory attached, such as a label

or ring.
On heat buildup
 Although the system heats up during

operation, this is not a malfunction.

 Place the system in a location with

adequate ventilation to prevent heat

buildup in the system.

 If you continuously use this system at a

high volume, the cabinet temperature rises

considerably. To avoid burning yourself, do

not touch the cabinet.

 To prevent a malfunction, do not cover the

ventilation openings.

Troubleshooting
