Cassette tapes should be properly
stored when not in use. It is recom ­
mended that cassettes be stored in a
cassette box designed to prevent
unwinding and the accum ulation of
dust.
If the cassette ejects during playback,
this may be caused by binding of the

to the beginning of the track.
P rotect cassette tapes from direct
sunlight or other tem perature
extremes.
