< Do not open a cassette or pull out the tape.
< Do not touch the tape.
< Do not use cassette tapes in an area with high-temperature and
humidity.
< Keep cassette tapes away from magnets or magnetized items
because they may cause noise or erase recorded contents.
< Do not leave cassette tapes in a dusty place.
< Do not store cassette tapes in an area with high-temperature and
humidity.
The following cassette tapes may prevent the unit from
performing normal operation or functions. The tape of such
cassette tapes may get caught and causing unexpected
problems.
Deformed cassettes, ones of which tape does not track properly,
or ones that generate abnormal noise during fast-forwarding or
rewinding.
Tapes for recording 90 minutes or longer sometimes get caught
by the capstan because they are extremely thin and stretch easily.
Avoid using them as much as possible.
Slackened tapes may get caught by the capstan or other parts.
Eliminate slack by using a pencil or alike before use.
There are several types of cassette tapes.
Metal (Type IV)
Chrome (Type II)
Normal (Type I)
< When playing a normal tape (type I), set the TAPE switch by the
turntable to NORMAL. When playing a chrome tape (type II) or
metal tape (type IV), set the switch to HIGH.
A dirty head causes poor sound quality or sound skip. Dirt on the
tape tracking roller may catch the tape. Clean the head, pinch
roller, and capstan with a cotton applicator dampened with a
commercially available cleaning solution about every ten hours
of use.
When the head is magnetized, it increases noise and hinders the
unit from transmitting high notes. When these problems occur,
demagnetize the head using a commercially available head
eraser.
Record/playback head
Do not set a cassette tape in the cassette holder of the unit until
the cleaning solution on the head dries.
