If you have any problem using this 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 have not
turned on the system (See step 6 of “Hooking up
the system” on page 9).
• Press DISPLAY twice when the system is turned
off. The demonstration disappears.
The clock setting/radio presetting/timer is
canceled.
• The power cord is disconnected or a power
failure occurs longer than half a day.
Redo the following:
— “Setting the time” on page 11
— “Presetting radio stations” on page 18
If you have set the timer, also redo “Waking up
to music” on page 26 and “Timer-recording radio
programs” on page 23.
There is no sound.
• Turn VOLUME clockwise (or press VOL + on
the remote).
• 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.
• There is no audio output during timer recording.
There is severe hum or noise.
• A TV or VCR is placed too close to the stereo
system. Move the stereo system away from the
TV or VCR.
• Connect the system to a different wall outlet.
• Install a noise filter (commercially available) to
the power line.
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
frequently. The tape may get entangled in the tape
deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use.
Be sure to clean the tape heads before you start an
important recording or after playing an old tape. Use
a 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.
