Make sure to clean the tape heads before you start an
important recording or after playing an old tape. Use
separately sold dry-type or wet-type cleaning cassette.
For details, refer to the instructions of the cleaning
tape.
Demagnetizing the tape heads
Demagnetize the tape heads and the metal parts that
have contact with the tape every 20 to 30 hours of use
with a separately sold demagnetizing tape. For
details, refer to the instructions of the demagnetizing
tape.
In case color irregularity is observed
in a nearby TV screen
With the magnetically shielded type of speaker
system, the speakers can be installed near a TV set.
However, color irregularity may still be observed in
the TV screen depending on the type of your TV set.
If color irregularity is observed...
Turn off the TV set once, then turn it on after 15 to 30
minutes.
If color irregularity is observed
again...
Place the speakers farther away from the TV set.
