Remote-Controlled Operation
When operating the remote control unit,
point it towards the remote sensor on the
front panel of the unit. (Fig. 4)
Battery Installation (Fig. 3)
1. Remove the battery compartment cover.
2. Insert two "AA" (R6, UM-3) dry batteries.
Make sure that the batteries are inserted
with their positive ± and negative —
poles positioned correctly.
3. Close the cover until it clicks.
Battery replacement
If the operation range from the unit to the
amplifier begins to decrease, the batteries
are nearly exhausted and both should be
replaced.
● Be sure to insert the batteries correctly,
as shown in the battery compartment.
● Do not use old and new batteries togeth-
er.
● Rechargeable and non-rechargeable
batteries can be used. Refer to the pre-
cautions on their labels.
● When the remote control unit is not to be
used for a long time (more than a month),
remove the batteries from the remote
control unit to prevent them from leak-
ing.

Maintenance (Fig. 5)
The heads and tape path should be cleaned
and demagnetized periodically.
Cleaning Tape Path
● Apply head cleaning fluid* to a cotton
bud or soft cloth, and lightly rub the
heads, capstan and all metal parts in the
tape path.
● Also clean the pinch roller using rubber
cleaning fluid*.
* Both are available in TEAC Tape
Recorder Cleaning Kits HC-2 and RC-2 in
the U.S.A. or TZ-261 in other areas.
Demagnetizing Heads
Be sure that the power is off, then demag-
netize the heads using a TEAC E-3 demag-
netizer. For details of its use, read its
instructions.
Caution:
If the surface of the unit gets dirty, wipe
with a soft cloth or use diluted neutral
cleaning liquid. Be sure to remove any fluid
completely. Do not use thinner, benzine or
alcohol as they may damage the surface of
the unit.

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?
● No audio output: Have all connections
been made correctly?
● Low sound quality: Are the heads dirty or
magnetized? Are you using good quality
tape? Has the correct NR System been
selected?
● Impossible to enter the record mode: Are
the record protection tabs of the cas-
sette in place?
