Precautions
Environment
Avoid using the deck in the following cir-
cumstances:
eHigh temperature (such as heater, direct
sunlight).
Extremely low temperature.
e Excessive humidity,
Dusty atmosphere.
Where power line voltage fluctuation is
severe (the use of a voltage regulator may
be advisable),
Be aware also that placing other units or
any objects on the deck can leave marks
depending on their weight.
Cassette Tape (Fig. 5)
Tape Selection:
For the automatic tape select function to
work properly, metal and chrome (cobalt)
formula tapes must have tape identification
holes,
C-120 cassette tapes:
120-minute tapes are very thin, they tend
to stretch and their magnetic layer is thin;
they also tend to introduce wow & flutter,
For these reasons, special attention is
required when using them. If the pinch
roller or capstan is dirty, tape might become
wrapped around it and this could cause
serious trouble, For this reason, it is re-
commended that you do not use C-120
tapes,
Tape Handling:
Do not store tape in the following places:
On top of heaters, in direct sunlight or in
any other high-temperature areas,
e Near speakers, on TV sets or amplifiers or
near any strong magnetic fields,
¢ High-humidity areas or dirty, dusty areas.
Avoid dropping or subjecting the cassettes
to excessive shock,
Voltage Conversion (For general export
models) (Fig. 6)
If it is necessary to change the voltage
requirements of the deck to match your
area, use the following procedure:
1. DISCONNECT POWER LINE CORD.
2. Using a screwdriver, turn the selector
until the desired voltage marking ap-
pears,

Notes:
To stop recording, press the STOP button.
To momentarily stop recording, press the
™ button. To resume recording, press
the > button or « button.
Note:
Recording prerecorded tapes, records, or
other published or broadcast material
may infringe copyright laws. Check
‘these laws before recording.
Setting the Recording Level
Setting the recording level correctly is es-
sential if you want to make top-quality
recordings. If the level is too low, the
recording will be noisy, If the level is set
too high, ‘the recording will be distorted.
Generally speaking, the recording level
should be set so that the loudest peak to be
recorded makes the meters briefty indicate
the meter reference reading for the type of
tape used. If the meters peak over the
reference reading, decrease the recording
level by turning the REC LEVEL control
counterclockwise. However, some program
material or different tape formulations may
require higher or lower recording levels.
With a little time and practice you will be
able to select the critical recording level
that gives you the best hi-fi recordings. The
optimum setting of the recording level will
differ according to the type and condition
of the tape, as well as the type of music
you are recording.
Using the BIAS FINE Tuning Control
The center position provides the standard
amount of bias current. Turning the control
toward “+” increases the amount of bias
current; a slight decrease in high-frequency
response will be obtained. Turning it toward
“" decreases the amount of bias current;
@ noticeable increase in high-frequency
response will be obtained.
1. Set the deck in the record mode and
begin recording by using a disc or a
Prerecorded tape the sound quality of
which you are familiar with,
2. Set the AUTO MONITOR button to
TAPE to monitor the reproduced sound.
If the high frequency sound seems
greater than the original, turn the BIAS
FINE tuning contro! toward “+” to ob-
tain the best possible sound. On the
other hand, if the high frequency sound
seems low, turn the control toward ‘-"
until the appropriate bias current is ob-
tained.
3. As a final check, alternately set the
AUTO MONITOR to SOURCE or TAPE
to confirm the correct setting of the
BIAS FINE tuning control by comparing
the recorded sound with the original.

Record Muting Operation —
The ability to leave blank unrecorded
(erased) portions on a tape during recording
is a real advantage in many recording
situations, For instance, you may want to
eliminate undesired portions of an FM
broadcast that you are recording, such as
commercials, station breaks or announce-
ments. You may want to record a complete
program with controlled spacing between
each song. Such blank portions on a tape
can be easily left using the REC MUTE
function.
1, Automatic Spacing operation — for a
4-secand blank — (during recording or
record-pause mode)
Press the REC MUTE button during the
recording or record-pause mode, The
tape continues to run, and a blank
space of about 4 seconds is recorded
(the REC indicator flashes).
The deck then switches automatically to
the record-pause mode (both the REC
and PAUSE indicators light). To start
recording the next tune, press the >
button or M™ button (both the REC
and PLAY indicators light).
For a Blank of More Than 4 Seconds
During recording, keep the REC MUTE
button pressed for a longer blank period,
Release the button to enter the record-
pause mode. To begin recording, press
the » button or ™ button.

SS SS SSS SSS
3. For a Blank of Less Than 4 Seconds
After pressing the REC MUTE button
during recording, press the " button,
before the 4-second interval has elapsed,
to cancel the muting mode and engage
the record-pause Mode. To begin record-
ing, press the ® button or # button.
Multi-Counter Function
With the multi-counter facilities incorporat-
ed in the unit, there are two different dis-
play modes available, depending on the
setting of the MODE button,
Tape Counter Mode: The counter functions
as a conventional tape counter.
TRT Counter mode: The counter functions
as a tape-run-time counter, measuring tape
travel in minutes and seconds,
Using as a Tape Counter
Using the MODE button, call up the tape
counter mode; a 4-digit display will appear.
Its function is identical to that of a conven-
tional tape indexing counter. During re-
cording (including record muting), playback
and fast-forward, the counter counts up as
the tape moves from left to right, and down
during rewind as the tape moves from
right to left, The indicated numerals are
not related to elapsed time and are not
compatible with the counter readings of
other cassette decks. One typical example
of using this display in the conventional
tape counter mode is: First load a cassette
and before recording, press the CLEAR
button to reset the counter to "0000".
Then note the counter reading at the begin-
ning of each piece of music to facilitate
locating that particular selection when
you wish to play it back.
Using as a TRT Counter
Using the MODE button, call up the tape-
run-time mode; “M” appears between the
2nd and 3rd digits and ““S” at the end of
the 4th digit. In this mode, tape travel is
measured in minutes and seconds while
the tape is running at normal speed during
recording (including record muting) and
playback. Counting stops during rewind
and fast-forward. This function can be
used to measure the approximate length
of a recorded song or to make an estimate
of how much tape is left.
“Visible” and “Invisible” Counters
Both counter modes are switchable at any
time, with the one selected appearing on the
display and the other functioning in memo-
ry, For example, when the conventional
tape counter is selected with the MODE
button, counting of the tape-run-time
also takes place and its reading can be
called up at any time by pressing the MODE
button. Pressing the CLEAR button resets
only the counter which is currently display-
ed, Both counters, “visible” and “‘invisible’*
are reset when power is switched off.
RTZ (Return To Zero) Function
To locate the position on the tape corres-
ponding to a tape counter reading of
“0000”, press the RTZ button.
The fast-forward or rewind of the tape
starts. When a counter reading of “0000”
is detected, the deck stops.
This function is handy to locate the begin-
ning of tune to be played back.
Fast-
Rewind : fornacd
+
To start playback from “0000”:
While the tape is running after the RTZ
button is pressed, press the > button.
The deck temporarily stops at the “0000"
counter reading, then playback starts.
To release the RTZ function:
Press the STOP button, If the <¢4 (rewind)
or > (fast-forward) button is pressed
while the tape is running after the RTZ
button is pressed, the RTZ function is re-
leased, and the deck enters the normal
rewind or fast-forward mode.
*The RTZ button cannot be used when the
deck is in the recording mode or near
the “0000” counter reading.

Remote Controlled Operation —
The provided RC-393 remote control unit
allows the V-3000 to be operated from a
distance. The control buttons on the remote
control unit function in almost the same
way as those on the front panel of the
V-3000, but they have slightly different
names, etc,
Precautions on Remote Control Operation
1. Battery Replacement (Fig.2)
1. Remove the lid.
2. Insert 2 “AA” type dry batteries.
Be sure that the batteries are inserted
with their negative and positive
terminals positioned correctly.
3. Close the lid until it clicks,
How often should the batteries be changed?
The batteries will normally last about six
months. However if you notice that the
distance between the remote control unit
and the V-3000 required for operation
becomes shorter, the batteries should be
changed. Replace the batteries with two
new ones.
Precautions Regarding Batteries
Be sure to insert the batte
positive (+) and negative
positioned correctly.
Never use old and new batteries together.
«Replacement batteries should be of the
same type. Never use batteries of different
types together.
e Rechargeable and non-rechargeable batte-
ries can be used. Refer to their precaution
labels.
Remove the batteries from the remote
control unit when it will not be used for a
long period of time.
When the batteries ara weak, replace them
as soon as possible.
Do not heat or disassemble batteries and
do not dispose of them by throwing them
into a fire,
with the
terminals
2. Remote Control Unit RC-393
When operating using the remote control,
point the front of the unit at the remote
sensor of the V-3000, The remote control
unit can be used within the range shown in
Fig. 3.

Note
Even if the remote control unit is operated
within the effective range, remote control
operation may be impossible if there is
any obstruction between the V-3000 and
the remote control unit.
elf the deck is operated in the vicinity of
other appliances generating infrared rays,
or if other remote control devices using
infrared rays are used near the V-3000,
the deck may operate incorrectly. Con-
versely, if the V-3000's remote control
unit is operated in the vicinity of other
appliances which use an infrared re-
mote control device, the other appliance
may operate incorrectly,
When the unit will not be used for a long
period of time (more than one month),
remove the batteries to prevent them
from leaking. If they do leak, wipe off the
liquid inside the battery compartment and
replace the batteries with new ones.
Do not place books or other objects on
the remote control unit as they could
press the buttons and discharge the
batteries,
Maintenance (Fig. 7)
The heads and tape path should be cleaned
and damagnetized periodically.
Cleaning 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 in TEAC HC-1 and
RC-1 in the U.S.A. or TEAC 12-261
Tape Recorder Cleaning Kit in other
areas,
Demagnetizing Heads
Be sure that the power is off, then demag-
netize the heads using a TEAC E-3 demay-
netizer or equivalent. For details of its
use, read its instructions,
Troubleshooting
a
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.

Dolby HX Pro is an “active bias" technique
that can improve the quality of audio tape
recordings. High-level high frequencies can
be recorded more accurately, without
sacrificing signal-to-noise ratio, while such
side effects of tape saturation as distortion
are reduced,
What Is Bias?
Bias is a very high-frequency signal generat-
ed within a tape deck and recorded on the
tape simultaneously with the program
material. This inaudible signal allows a low
noise, low distortion recording and flat
frequency response. Different magnetic tape
formulations require different amounts
of bias for optimum performance. If the
bias level is too high, high-frequency
Maximum Output Level (MOL) decreases.
The Problem of Self-Bias
Unfortunately, bias level is often influenced
by the signal being recorded. The high fre-
quencies contained in some music act as
bias. This unpredictable source of bias is
added to the existing bias, resulting in a loss
of high-frequency response. As the high-
frequency content of the signal increases,
eNo audio output. Are all connections
properly made?
Degraded sound quality: Are the heads
dirty or magnetized? Are you using
good quality tape? Is the proper NR
System select switch on?
eUnable to select record mode: Are the
record protection tabs on the tape in
place?
the ability of the recorder to record high
frequencies (MOL) decreases. This pheno-
menon is called self-biasing.
How Dolby HX Pro Solution
The Dolby HX Pro monitors the high-
frequency content of the program material
and adjusts the recorder bias oscillator to
maintain a constant total bias level. The
result is improved high-frequency response
and lower distortion. Depending on the type
of tape, the improvement in headroom can
be 6 dB or more.
The Benefits
With Dolby HX Pro, it is easier to make
More accurate recordings of the kind of
music which contains high-level high fre-
quencies. The improvement is similar to
that of high-performance tape over conven-
tional tape, so regardless of the type of
tape used, the results will sound better.
Most important of all, Dolby HX Pro
requires no decoding process. Once the
tape is recorded with it, the improvements
will be realized when playing the tape back
on any machine.
