Additional Information
Pre ca u t io n s
On safety
• Since a strong magnet is used for the
speakers, keep personal credit cards
using magnetic coding or spring-
wound watches away from the player
to prevent possible damage from the
magnet.
Should any solid object or liquid fall into
the player, unplug the player, and have
it checked by qualified personnel before
operating it any further.
On pow er sources
On operation
• For AC operation, use the supplied
AC power cord; do not use any other
type.
If the player has not been used for a long
time, set it in the playback mode to
warm it up for a few minutes before
inserting a cassette.
• The player is not disconnected from
the mains as long as it is connected to
the mains, even if the player itself has
been turned off.
If you have any questions or problems
concerning your player, please consult
your nearest Sony dealer.
• For battery operation, use four R20
(size D) batteries.
Notes on cassettes
• Break off the cassette tab from side A
or B to prevent accidental recording.
If you want to reuse the tape for
recording, cover the broken tab with
adhesive tape.
• When the batteries are not to be used,
remove them to avoid damage that
can be caused by battery leakage or
corrosion.
• The nameplate indicating operating
voltage, power consumption, etc. is
located at the bottom.
Side A
On placement
• Do not leave the player in a location
near heat sources, or in a place subject
to direct sunlight, excessive dust or
mechanical shock.
Tab for side A
Tab for side B
• To record on a tape with its tab broken
off, cover the respective tab hole for
side A or B with adhesive tape.
• Do not place the player on an inclined
or unstable place.
• The use of a cassette with more than
90 minutes of play time is not
recommended except for long,
continuous recording or playback.
• Do not place anything within 10 mm
of the side of the cabinet. The
ventilation holes must be
unobstructed for the player to operate
properly and prolong the life of its
components.
• If the player is left in a car parked in
the sun, be sure to choose a location in
the car where the player will not be
subjected to the direct rays of the sun.
