Precautions (continued)
Before placing a cassette in the tape
deck
Take up any slack in the tape. Otherwise the tape may
get entangled in the parts of the tape deck and become
damaged.
When using a tape longer than 90
minutes
The tape is very elastic. Do not change the tape
operations such as play, stop, and fast-winding, etc.
frequently. The tape may get entangled in the tape
deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use.
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
cassette.
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 cassette. For
details, refer to the instructions of the demagnetizing
cassette.
In case color irregularity is observed
on nearby a 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 on
the TV screen depending on the type of your TV set.
If color irregularity 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.
