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 aren't, they may not operate'
properly or cause failure of the tape player.
Your tape player should be cleaned regularly each
month or after every 15 hours of use. If you notice 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.
Clean your tape player with a wiping-action,
non-abrasive cleaning cassette, and follow the directions
provided with it.
Cassettes are subject to wear and the sound quality may
degrade over time. Always make sure that the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution an
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
