an inability of the unit to record or play tapes.
For details, refer to the instructions of the
cleaning cassette.

Demagnetizing the tape heads

Use a demagnetizing cassette (available

Failure to demagnetize the tape heads can
cause an increase in noise, a loss of high
frequency sound, and an inability to completely
erase tapes. For details, refer to the instructions
of the demagnetizing cassette.
