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.
If you have any questions or problems concerning
your stereo system, 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 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.
Additional Information
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. If you later want to reuse the tape for
recording, cover the broken tab with adhesive tape.
When you are using a TYPE II (CrO
2
) or TYPE IV
(metal) cassette, be careful not to cover the detector
slots which allow the tape player to automatically
detect the type of 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.
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.
