Features
Precautions
General
•If your car is parked in direct sunlight
resulting in a considerable rise in
temperature inside the car, allow the unit to
cool off before operating it.
•If no power is being supplied to the unit,
check the connections first. If everything is in
order, check the fuse.
•If no sound comes from the speakers of a
2-speaker system, set the fader control to the
center position.
•If your car is equipped with a power
antenna, note that it will be automatically
extended while the unit is operating.
• Detachable-front panel enables you to take
the front panel away with you when you
leave your car (page 4).
• Caution alarm will be activated if you turn
off the ignition key without removing the
front panel from the unit.
• Built-in power amplifier (max. output:
15 W × 4 ch) enables you to enjoy a
4-speaker system.
•Digital 24-hour clock provided (page 5).
Tuner section
• Up to 30 stations can be preset: 18 stations on
FM, 6 stations each of MW and LW.

Notes on Cassettes
Table of Contents
Cassette care
Detaching and Attaching the Front Panel ............ 4
Setting the Clock ...................................................... 5
•Do not touch the tape surface of a cassette, as
any dirt or dust will contaminate the heads.
•Keep cassettes away from equipment with
built-in magnets such as speakers and
amplifiers, as erasure or distortion of the
recorded tape could occur.
•Do not expose cassettes to direct sunlight,
extremely cold temperatures, or moisture.
•When the tape is played back for a long
period, the cassette shell may become warm
because of the built-in power amplifier. This
is not a sign of a malfunction.
Notes on Cassette Deck Tape Heads
•Long use of cassette tapes contaminates the
tape head causing poor sound quality or
complete sound dropout. Therefore, we
recommend cleaning the tape head once a
month or so with the separately available
Sony Cassette Cleaning Set. If the sound does
not improve after using a cleaning cassette,
please consult your nearest Sony dealer.
•In case of old or inferior cassette tapes, the
tape head gets contaminated much more
quickly. Depending on the tape, one or two
playbacks may cause poor sound.
Cassettes longer than 90 minutes
The use of cassettes longer than 90 minutes is
not recommended except for long continuous
play. The tapes used for these cassettes are
very thin and tend to be stretched easily.
Frequent playing and stopping of these tapes
may cause them to be pulled into the cassette
deck mechanism.
