Automatic tape type detection function

This cassette deck can detect what type of tape is being used based
on the detection holes in the cassette shell. Be sure to use cassettes
with detection holes.
With this cassette deck, you can play back normal (Type I), chrome
(Type II) and metal (Type IV) tapes. For recording, use normal (Type I)
or chrome (Type II) tapes.
Each deck (TAPE I and TAPE II) is equipped with its own auto tape
type detection function, so you can use different types of tape at the
same time.

Tape slack

Slack can cause the tape to get tangled in the capstan or other
rotating parts. To prevent this, take up all tape slack using a pencil or
the like inserted into the reel hole.

Accidental erasure prevention tabs

Tabs on top of the cassette shell allow you to prevent important
recordings from being erased by mistake. There are two tabs on each
cassette shell: one for side "A" and the other for side "B".
Once these tabs have been removed using a screwdriver or the
like, there is absolutely no chance of the recording function being
activated.
To record on a cassette whose tab has been broken off, stick a piece
of adhesive tape over the hole. Be careful not to block the tape type
detection holes.

Maintenance

If the surface of the deck becomes soiled, wipe it clean with a dry,
soft cloth. Never use volatile cleaners like thinners, benzine or alcohol
because they will damage the surface finish.
Do not allow the deck to remain in contact with rubber or vinyl
products for a long period of time, as these could damage the surface
finish.
CAUTION
For safety, always unplug the power cord before performing any
maintenance.
< Cleaning the heads
If the head section gets dirty, the recording quality will deteriorate,
resulting in degraded playback sound or "drops" in sound. Also,
if the tape transport path gets dirty, the tape may get entangled
in the rotating parts. It is therefore recommended that the heads,
pinch rollers and capstans be cleaned regularly at intervals of
10-hour use with a cotton swab moistened with a commercially
available, appropriate cleaning liquid.
NOTE
Do not make a recording or play back tape when the tape
transport path is wet with cleaning liquid, as this could cause the
tape to jam or clog.
