Troubleshooting

If you run into any problem using this stereo

system, use the following check list.

First, check that the power cord is connected

firmly and the speakers are connected

correctly and firmly.

Should any problem persist, consult your

nearest Sony dealer.

General

The display starts flashing as soon as you

plug in the power cord even though you

haven’t turned on the power

(demonstration mode).

•Press DISPLAY/DEMO when the power

is turned off.

The demonstration mode appears

automatically the first time you plug in

the power cord. If there is a power outage

lasting longer than half a day, redo the

following:

— Clock setting (see “Step 2: Setting the

time”)

— Preset stations (see “Step 3: Presetting

radio stations”)

— Timer settings (see “Waking up to

music” and “Timer recording radio

programmes”).

There is no sound.

•Rotate VOLUME clockwise.

•The headphones are connected.

•Insert only the stripped portion of the

speaker cord into the SPEAKER jack.

Inserting the vinyl portion of the speaker

cord will obstruct the speaker

connections.

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.

When the tape heads become dirty

— the sound is distorted

— there is a decrease in sound level

— the sound drops out

— the tape does not erase completely

— the tape does not record

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.
