Maintenance (Fig. 7)
The heads and tape path should be cleaned
and demagnetized periodically.
Cleaning the Tape Path
eApply
head
cleaning fluid* to special
cotton swabs or a soft cloth, and lightly
rub the heads, capstans and all metal
parts in the tape path,
Also clean the pinch rollers using rubber
cleaning fluid*
* Both are available as TEAC HC-1 and RC-
1 in the U.S.A. or in the TEAC TZ-261
Tape Recorder Cleaning Kit in other areas.
Demagnetizing Heads
Be sure that the power is off, then demagne-
tize the heads using a TEAC E-3 demagne-
tizer or equivalent. For details of its use,
read its instructions.
Troubleshooting
Basic troubleshooting
of a cassette tape
deck is similar to troubleshooting any other
electrical or electronic equipment. Always
check
the most obvious possible causes
first. To give you a few ideas of what to
look for, check the following:
« No power: Is the power cord connected?
Tape begins running when power is turned
on, Is the TIMER function switched on?
«No audio output. Have all connections
been done correctly?
Degraded
sound
quality: Are the heads
dirty or magnetized?
Are you using good
quality tape?
Is the NR selector in the
correct position?
Unable to select the record mode: Are
the record
protection
tabs of the tape
in place?
