Additional Information

Precautions

On operating voltage

Before operating the unit, check that the operating
voltage of your unit is identical with the voltage of
your local power supply.

On safety

• The unit is not disconnected from the AC power
source (mains) as long as it is connected to the wall
outlet, even if the unit itself has been turned off.

• Unplug the unit from the wall outlet (mains) if it is
not to be used for an extended period of time. To
disconnect the cord (mains lead), pull it out by the
plug. Never pull the cord itself.

• Should any solid object or liquid fall into the
component, unplug the unit and have the
component checked by qualified personnel before
operating it any further.

• The AC power cord must be changed only at the
qualified service shop.

On placement

• Place the unit in a location with adequate
ventilation to prevent heat build-up in the unit.

• Do not place the unit in an inclined position.

• Do not place the unit in locations where it is:
— extremely hot or cold
— dusty or dirty
— very humid
— vibrating
— subject to direct sunlight

On heat buildup

• Although the unit heats up during operation, this is
not a malfunction.

• Place the unit in a location with adequate
ventilation to prevent heat build-up in the unit.

If you use this unit at a large volume, the cabinet
temperature of the top, side and bottom rises
considerably. To avoid burning yourself, do not touch
the cabinet.
To prevent a malfunction, do not cover the ventilation
hole for the cooling fan.

On operation

• If the unit is brought directly from a cold to a warm
location, or is placed in a very damp room, moisture
may condense on the lens inside the CD player.
Should this occur, the unit will not operate properly.
Remove the CD and leave the unit turned on for
about an hour until the moisture evaporates.

• When you move the unit, take out any discs.

If you have any questions or problems concerning
your unit, please consult your nearest Sony dealer.

Notes on CDs

• Before playing, clean the CD with a cleaning cloth.
Wipe the CD from the center out.

• Do not use solvents.

• Do not expose the CD to direct sunlight or heat

sources.

• Discs with non-standard shapes (e.g., heart, square,
star) cannot be played on this unit. Attempting to do
so may damage the unit. Do not use such discs.

Note on CD-R/CD-RW playback

Discs recorded on CD-R/CD-RW drives may not be
played back because of scratches, dirt, recording
conditions or the drive's characteristics. Besides, the
discs which are not yet finalized at the end of
recording, cannot be played back.

Cleaning the cabinet

Use a soft cloth slightly moistened with mild
detergent solution.

To save a tape permanently

To prevent a tape from being accidentally recorded
over, break off the cassette tab. Refer to the
instructions of the tape.

Before placing a cassette in the tape
deck

Take up any slack in the tape. Otherwise the tape may
get entangled in the parts of the tape deck and become
damaged.

When using a tape longer than 90
minutes

The tape is very elastic. Do not change the tape
operations such as play, stop, and fast-winding etc.
frequently. The tape may get entangled in the tape
deck.

Cleaning the tape heads

Clean the tape heads after every 10 hours of use.
Make sure to clean the tape heads before you start an
important recording or after playing an old tape. Use
separately sold dry-type or wet-type cleaning cassette.
For details, refer to the instructions of the cleaning
cassette.

Demagnetizing the tape heads

Demagnetize the tape heads and the metal parts that
have contact with the tape every 20 to 30 hours of use
with a separately sold demagnetizing cassette. For
details, refer to the instructions of the demagnetizing
cassette.
