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 n\
o
improvement in sound quality, clean the tape player.
