2. Installation
1) Avoid placing the unit on or adjacent to an amplifier, to
prevent hum from being produced by some types of
amplifiers. Move the unit to a place not affected by the
amplifier. Keep the unit as far as possible from a TV set.
2) Avoid installing the unit in a-location. subject to ambient
temperatures
exceeding
40°C (104°F) (e.g. direct
sunlight, near heaters, etc.) or less than 0°C (32°F),
excessive humidity, dust or vibrations.
3) If this set is moved suddenly from a cold place (0°C) to a
warm
place, it may not function properly because of
moisture generated inside the unit. The unit will function
properly 30 minutes after being moved.
3. Cleaning the cabinet
Never use benzine or thinner for cabinet cleaning as they
may damage the surface finish.
4. Cassette tape
1) Loose tape may become tangled in the tape transport
mechanism.
Remove
slack by winding the tape with a
pencil. (Fig. 2)
Fig. 2
Turn the pencil to tighten the tape.

tape
is not
recommended,
since
characteristic
deterioration may occur.

4) Do not store cassette tapes where there is a magnetic
field (e.g. near a TV, etc.) or in a place subject to high
temperatures or humidity.
5. Auto tape select mechanism (decks A and B)
This deck has an Auto Tape Select mechanism which
distinguishes between different types of tape from holes in
the cassette. After the type of tape has been detected,
bias and equalization are set to be suitable for the tape.
e Cassettes with the detection holes:
Metal tape (EQ: 7OUS) ..........sseeceeeceseeteneeetenes Type IV
CrO,(chrome) tape (EQ: 70S) ..........cereeeeeeeees Type Il
e Cassettes without the detection holes:
Normal tape (EQ: 120pS)........:scsccsseseerserseeesens Type |
Some earlier types of metal and CrO, (chrome) tapes
may not be provided with the detection holes. Avoid using
such tapes, since correct equalization characteristics
cannot be obtained. Also do not use ferrichrome tapes
whose characteristics do not match this unit.
