Tape position indentification holes.

IMPORTANT :

Do not use C-120 tape.

Head demagnetization

The head assembly should be demagnetized after about
each 50 hours of use in order to maintain good sound
quality.
The head assembly becomes magnetized, causing noise in
recordings and unwanted erasure of valuable recordings, if
a magnetized screwdriver or other metal tools come near
the head assembly, and when the heads have been used
for a long period of time. If the heads become magnetized,
use a head demagnetizer (option).

When demagnetizing the head assembly, be sure to first
push the power switch to the “off” position.

Maintenance of external surfaces

To clean, use a soft dry cloth.
If the surfaces are extremely dirty, use a soft cloth, dipped
into a soap and water solution or a weak detergent solution.
Wring cloth well before wiping the unit.
Wipe once again with a soft dry cloth.
Never use alcohol, paint thinner, benzene, or a chemically
treated cloth to clean this unit.
Such chemicals may damage the finish of your unit.

Maintenance of the cassette tape

Observe the following to prevent the tape from being twisted.

Don’t pull the tape out of the upper opening of the cas­sette tape.
If the tape is wound loosely inside the cassette, use the
tape deck on fast forward or reverse to tighten.
If a small portion of tape is unwound from the cassette,
make the tape tight as shown in the figure below.

Cleaning with a Head Cleaning Tape

Insert a Head Cleaning Tape into the cassette deck.
Turn the power on, press PLAY button and the surface of
the head will be cleaned in a short time.

Maintenance of the head section

The head assembly, capstans and pinch rollers should be
cleaned after about each 10 hours of use in order to main­tain good sound quality.

Cleaning with a cotton swab

(If the parts are
very dirty, use a
small amount of
alcohol on the
cotton swab.)

Use a pencil to take
up the slack and
rotate it in the arrow
direction.

Environment

Avoid using the deck in the following conditions:

At high temperatures (near a heater, exposed to direct
sunlight, etc.)
At extremely low temperatures.
Where there is excessive humidity.
