What is the Radio Data System?

Radio Data System (RDS) is a broadcasting
service that allows radio stations to send
additional information along with the regular
program signal. This tuner offers convenient
RDS features like station name display and
location of stations by program type. RDS is
available only on FM stations.*

Note

RDS may not work properly if the station you are
tuned to is not transmitting the RDS signal properly
or if the signal strength is weak.
* Not all FM stations provide RDS service, nor do

they provide the same type of services. If you are
not familiar with the RDS system, check with your
local radio stations for details on RDS services in
your area.

Additional Information

Precautions

On operating voltage

Before operating the system, check that the
operating voltage of your system 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 system 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 stereo system 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 stereo system in a location with adequate
ventilation to prevent heat build-up in the stereo
system.

• 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 operation

• If the stereo system 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 system will
not operate properly. Remove the CD and leave
the system turned on for about an hour until the
moisture evaporates.

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

Notes on CDs

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

• Do not use solvents such as benzene, thinner,
commercially available cleaners or anti-static
spray intended for vinyl LPs.

• Do not expose the CD to direct sunlight or heat
sources such as hot air ducts, nor leave it in a car
parked in direct sunlight.

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 from side A or B as
illustrated.

Detector slots

Tab of side B

If you later want to reuse the tape for recording,
cover the broken tab with adhesive tape. However,
be careful not to cover the detector slots which allow
the tape player to automatically detect the type of
tape.

Tab of side A

Side A

Break off the
cassette tab of
side A

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

Precautions (continued)

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.

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
programs”).

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.

44

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.

The sound from the connected source is
distorted.

•If “VIDEO” appears in the display when
you press FUNCTION, switch the display
to “MD” (see “Note: Connecting a VCR”).

“0:00” (or “12:00”) flashes in the display.

•A power interruption occurred. Set the
clock and timer settings again.

The timer does not function.

•Set the clock correctly.

DAILY1, DAILY 2, and REC do not appear
when you press the TIMER SELECT button.

•Set the timer correctly.

•Set the clock.

The remote does not function.

•There is an obstacle between the remote
and the system.

•The remote is not pointing in the
direction of the system’s sensor.

•The batteries have run down. Replace the
batteries.

There is acoustic feedback.

•Decrease the volume level.

•Move the microphone away form the
speakers or change the direction of the
microphone.

The color irregularity on a TV screen
persists.

•Turn off the TV set once, then turn it on
after 15 to 30 minutes. If the color
irregularity still persists, place the
speakers farther away from the TV set.

Speakers

Sound comes from one channel or
unbalanced left and right volume.

•Check the speaker connection and
speaker placement.

Sound lacks bass.

•Check that the speaker’s + and – jacks are
connected correctly.

CD Player

The CD tray does not close.

•The CD is not placed properly.

The CD will not play.

•The CD is not lying flat in the disc tray.

•The CD is dirty.

•The CD is inserted label side down.

•Moisture condensation has built up.
Remove the CD and leave the system
turned on for about an hour until the
moisture evaporates.

Play does not start from the first track.

•The player is in program or shuffle mode.
Press PLAY MODE repeatedly until
“PROGRAM” or “SHUFFLE” disappear.

“OVER” is displayed.

•You have reached the end of the CD.

Tape Deck

The tape does not record.

•No tape in the cassette holder.

•The tab has been removed from the
cassette (see “To save a tape
permanently” on page 43).

•The tape has reeled to the end.

The tape does not record nor play or there
is a decrease in sound level.

•The heads are dirty. Clean them (see
“Cleaning the tape heads” on page 44).

•The record/playback heads are
magnetized. Demagnetize them (see
“Demagnetizing the tape heads” on page

44).

The tape does not erase completely.

•The record/playback heads are
magnetized. Demagnetize them (see
“Demagnetizing the tape heads” on page

44).

There is excessive wow or flutter, or the
sound drops out.

•The capstans or pinch rollers are dirty.
Clean them (see “Cleaning the tape
heads” on page 44).

Noise increases or the high frequencies are
erased.

•The record/playback heads are
magnetized. Demagnetize them (see
“Demagnetizing the tape heads” on page

44).

After pressing ( (9) or §, there is a
mechanical noise, “EJECT” appears in the
display, and the unit enters standby mode
automatically.

• The cassette tape was not inserted
correctly. Eject the tape and turn the
power back on.

Severe hum or noise (“TUNED” or
“STEREO” flashes in the display).

•Adjust the antenna.

•The signal strength is too weak. Connect
the external antenna.

A stereo FM program cannot be received in
stereo.

•Press STEREO/MONO so that “STEREO”
appears.

If other troubles not described
