Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes, or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight, and
extreme heat. If they are not, they may not operate
properly or may cause failure of the tape player.
The tape player should be cleaned regularly after every
50 hours of use. The radio may display CLN to
indicate that the tape player has been used for 50 hours
without resetting the tape clean timer. If CLN appears
on the display, the cassette tape player needs to
be cleaned. It will still play tapes, but it should be
cleaned as soon as possible to prevent damage to the
tapes and player. If there is a reduction in sound
quality, try a known good cassette to see if the tape or
the tape player is at fault. If this other cassette has
no improvement in sound quality, clean the tape player.
For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer.
The cut tape detection feature of the cassette
tape player may identify the cleaning cassette as a
damaged tape, in error. If the cleaning cassette ejects,
insert the cassette at least three times to ensure
thorough cleaning.
A non-scrubbing action, wet-type cleaner which uses a
cassette with a fabric belt to clean the tape head
can be used. This type of cleaning cassette will not
eject on its own. A non-scrubbing action cleaner may not
clean as thoroughly as the scrubbing type cleaner.
The use of a non-scrubbing action, dry-type cleaning
cassette is not recommended.
After the player is cleaned, press and hold the EJECT
button for five seconds to reset the CLN indicator.
The radio will display --- to show the indicator was reset.
Cassettes are subject to wear and the sound
quality may degrade over time. Always make sure the
cassette tape is in good condition before the tape player
is serviced.
