To restore the sound quality, fast-forward
the tape from the beginning to the end of
one side, then completely rewind it. Then
loosen the tape reels by gently tapping
each side of the cassette’s outer shell on a
flat surface.
Caution: Be careful not to damage the
cassette when tapping it. Do not touch the
exposed tape or allow any sharp objects
near the cassette.

record as usual. The cassette deck
records over the previous recording.
