Tape editing
1. Press the

REC/REC MUTE button when finished dubbing

a tune. Deck B automatically enters the record muting mode
and leaves a non-recorded section of about 4-seconds then
enters the record-paused mode.

2. Press the

(stop) button of deck A and search for the next

tune you want by using the

,

or PLAY button. Then

stop the cassette just before the beginning of the tune.

3. Press the same SYNCHRO DUBBING button pressed

before the pause again, and dubbing will start.

Notes at dubbing
1. Normal-speed dubbing is recommended to obtain good

sound quality.

2. Television receivers placed close to the deck may cause

interference on the recorded signal when the deck is used in
the high-speed dubbing mode. If this happens, either turn off
the television receiver or use the normal-speed dubbing
mode.

MAINTENANCE

The importance of cleaning
When the tape is moving, magnetic powder and dust naturally
accumulate on the heads, capstan and pinch roller. When they
become too dirty.

tone quality deteriorates.

the output sound level drops.

the previous sound is not erased satisfactorily.

recordings are not satisfactory.

Because of this, clean the heads, etc. every 10 hours of use so
that optimum recordings will be made.

Cleaning the heads, pinch roller and capstan

Wipe the heads, the capstan, etc. with a cotton swab with its tip
dipped in alcohol. For effective cleaning, use a cleaning kit avail-
able from your audio store. After cleaning, be sure that the
cleaning fluid has completely dried before loading a cassette.

Demagnetizing the heads
Magnetic objects brought close to the head or using the deck for
a long period of time, results in magnetization of the head, thus
noise occurs. When the noise is excessive, high frequencies on
the recorded tape may be erased.
Demagnetize the heads and other metal parts that come into
contact with the tape every 20–30 hours of use with a head
demagnetizer (available from your audio store).

TROUBLESHOOTING

What appears to be trouble is not always real trouble. Make
sure first....
1. Cassette cannot be loaded.

Is the cassette positioned correctly?

2. When PLAY button is pressed, tape does not move.

Is the tape too loosely wound?

3. Tape runs, but no sound is heard.

Are all connections properly and securely made?

Is the MONITOR switch of the stereo amplifier set to the
TAPE position?

Is the VOLUME control of the stereo amplifier set to MIN?

4. Sound quality is poor.

Is the DOLBY NR switch set to the right position?

Is the head section dirty?

Is the record/playback head magnetized?

Is the tape worn out?

5. Recording cannot be performed.

Are the safety tabs of cassette tape broken?

Are all connections properly and securely made?

Is the head section dirty?

6. Previous recording is not completely erased.

Is the erase head dirty?

7. Since tape speed is irregular, wow and flutter occur.

Is the pinch roller or capstan dirty?

Is the tape rewound too tight?
