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)
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.
•
Cassettes with the detection holes:
Metal tape (EQ: 70µs) ........................................ Type IV
CrO

(chrome) tape (EQ: 70µs) .......................... Type II
•
Cassettes without the detection holes:
Normal tape (EQ: 120µs) ..................................... Type I
2
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 ferrochrome tapes whose characteristics do not match this unit.

Turn the pencil to tighten the tape.
2) The use of C-120 (120 minutes turn around) or thinner tape
is not recommended, since characteristic deterioration may
occur.
3) To prevent recordings from being erased accidentally,
remove the tab(s) with a screwdriver. Reseal the slots with
adhesive tape to erase and re-record after the tabs have
been broken off.
