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 3: Setting the

time”)

— Preset stations (see “Step 4: Presetting

radio stations”)

— Timer settings (see “Waking up to

music” and “Timer recording radio
programs”).

“12:00 AM” flashes in the display.

•A power interruption occurred. Set the

clock and timer settings again.

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.
