Notes on Cassettes
Cassette care
•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.
