TOA Electronics AM-821 - Manual (Page 3)

PRECAUTIONS
1. Avoid setting up unit in the locations exposed to direct sunlight, or heaters or other heat sources, or with
high humidity or dust.
2. The cassette tape can last only 200 hours on average. After 200 hours of use, replace the tape with the
new one.
3. Do not use the C-120 cassette tape. (You may use other normal tapes.)
USER CARE
1. CLEANING THE HEAD SECTION
If the head, capstan or pinch roller gets dirty or accumulates dust, the deterioration of the sound quality or
unstable operation will result. An occasional wiping down with soft cloth damped with alcohol is
recommended to keep unit in good shape.
2. DEMAGNETIZING THE HEAD
The recording head becomes magnetized when the recorder is used for prolonged periods of time. This
results in noise being generated and the treble dropping off during recording. So, the recording head
should be regularly demagnetized with the head eraser.
3. HANDLING CASSETTE TAPES
The AM-821 can accept normal tape only. Do not use chrome or metal tapes to avoid loss of sound
quality.
Do not use the C-120 cassette tape. Since the it is thin and easily damaged, they may stretch during use
causing unstable tape movement which may result in the tape becoming tagled in the rotating parts of
this unit.
Do not use tapes which have been stored in a hot moist place or close to a television or speaker. Such
tapes may curl or have greasy places altering tape speed and preventing proper tape performance.
Always store in a cool, dry place which is free from dirt, oil and magnetic effects.
Before using a tape, check to confirm if tape slack exists. Because the tape slack causes the tape twist
or tangle around the pinch rollers and capstans, take up the slack, if necessary, by inserting a pencil
through the reel hub and turning it.
To prevent erasing of recorded sounds, remove the erase-prevention tabs using a screwdriver or similar
object to break out the tab (thus preventing recording). To record again, cover the slot with adhesive
tape.
The cassette tape can last only 200 hours on average. After 200 hours of use, replace the tape with the
new one.
4. CLEANING THE FRONT PANEL
Use a soft cloth to wipe off dust and grease of the front panel and cassette receptacle covers. When they
are very dirty, damp the soft cloth slightly with neutral cleanser, remove the dirt and wipe with a dry cloth.
Never use volatile spirits like thinners, benzines or alcohol because they will damage the panel's finish.
5. Avoid setting up the recorder in the locations exposed to direct sunlight, or near heaters or other heat
sources, or in areas of high humidity or dust.
