Selection of cassette tapes
You can use normal, chrome, and metal tapes for recording:
oThe deck automatically identifies the kind of tape loaded, and sets
the bias (for recording) and equalization accordingly.
oThe deck automatically sets the recording level.
Cassette tapes exceeding 90 minutes:
These tapes are handy for their long playback and recording time but
be careful about repeatedly stopping and starting, rewinding and fast
forwarding these tapes in short intervals as they are thin, tend to
stretch and may become entangled in the deck mechanism.
Do not use the Fe-Cr tapes (TYPE lll) in this system:
If you use this tape, it is impossible to obtain the required flat
frequency response.
If the tape loosens, take up the slack
Tape slack may cause the tape to break.
