CD Synchro Dubbing (Fig. 1)
By connecting the deck to a TEAC CD
synchro compatible CD player which has a
CD/DECK SYNC terminal on its rear panel,
dubbing (recording) synchronized with the
CD player is possible.
Frowarstog
Connect the deck's CD/DECK SYNC
terminal to the CD player's CD/DECK
SYNC terminal using an optional cable.
2. Perform programming of the ‘time edit’,
etc. functions of the CD player
beforehand (refer to the instructions of
the CD player).
3. Set the source to CD using the
amplifier's source select buttons.
4, Set the recording level.
5. Set the deck and the CD player to the
stop mode.
6. Press the CD SYNC button of the deck.
The CD player will start automatically
approx. 1 sec after the deck starts
recording and dubbing will be
performed. (The CD SYNC indicator
lights.) (See page 7.)
To stop temporarily during dubbing:
To temporarily stop CD synchro dubbing
(A) Press the STOP button of the deck. The
CD player will return to the beginning
of the current tune and pause there. To
restart, press the deck's CD SYNC
button.
(B) Press the stop button of the CD player.
The deck enters the rec/pause mode.
To restart, press the CD player's play
button.
When the CD player has entered the
pause mode, it stands by after returning
to the beginning of the tune that has just
been played.
When recording is done up to the end of
the tape, the CD player stands by after
returning to the beginning of the tune
that has just been played.
Note:
If the CD player is connected to the stereo
amplifier using an optical cable, synchro
dubbing is not possible. If synchro dubbing
is required, you must connect the deck's
analog output using pin plug cords.
CAUTION:
Recording pre-recorded tapes, records,
or other published or broadcast
material may infringe copyright laws.
Check these laws before recording.
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 “AAA (R03, UM-4) dry
batteries.
Make sure that the batteries are
inserted with their positive ® and
negative © poles positioned correctly.
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
together.
@ Rechargeable and non-rechargeable
batteries can be used. Refer to the
precautions 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
leaking.
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
demagnetize the heads using a TEAC E-3
demagnetizer. 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
cassette in place?
