Precautions

Features and Controls (Fig. i)

Environment

Avoid using the deck in the following cir­cumstances:

• High temperature (such as heater, direct
sunlight).

• Extremely low temperature. ^ ^'^ '

• 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.

• Near speakers, on TV sets or amplifiers or

near any strong magnetic fields.

• High-humidity areasordirty, 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 ap­pears.

6. Press the RECORD button (both the

REC and PAUSE indicators light). This
enables you to adjust the recording level
without actually recording on the tape.

7. Adjust the REC LEVEL and BALANCE
controls so that the loudest peak briefly
reaches the meter reference reading

for the type of tape used for both chan-

nels.

8. Adjust the BIAS FINE tuning control
described in "Using the BIAS FINE
Tuning Control".

9. Press the • button or ii button to
start recording. The REC and PLAY

indicators light.

The Auto Monitor indicator is auto-

matically changed to TAPE and the

signal can be directly monitored im-

mediately after it is recorded. To com­pare the recorded sound with the
original source, press the AUTO
MONITOR button to switch the signal
being monitored between TAPE and

SOURCE.

Notes:

• To stop recording, press the STOP button.

• To momentarily stop recording, press the
II button. To resume recording, press

the •• button or ii 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 es­sential 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;

a 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 control toward "+" to ob­tain 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 ob­tained. -^ • '

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.

Erasing

A previously recorded tape will be auto­matically erased when you make a new
recording on it. Alternatively it can be
erased by "recording" on it with the REC

LEVEL control set to "°°".

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 announce­ments. 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-second 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

g and PAUSE indicators light). To start

.} recording the next tune, press the •

'. button or ii button (both the REC

and PLAY indicators light).

2. For a Blank of More Than 4 Seconds

3 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.

-7-

3. For a Blank of Less Than 4 Seconds
After pressing the REC MUTE button
during recording, press the n 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 ii button.

Multi-Counter Function

With the multi-counter facilities incorporat­ed in the unit, there are two different dis­play modes available, depending on the
setting of the MODE button.
Tape Counter Mode: The counter functions
as a conventional taps 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 conven­tional tape indexing counter. During re­cording (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 memo­ry. 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 display­ed. Both counters, "visible" and "invisible"
are reset when power is switched off.

RTZ (Return To Zero) Function

To locate the position on the tape corres­ponding 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 begin­ning of tune to be played back.

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 -•^ (rewind)
or •»• (fast-forward) button is pressed
while the tape is running after the RTZ
button is pressed, the RTZ function is re­leased, 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.

Timer-Controlled Operations(Fig.8)

Timer-Controlled Recording

1. Connect your deck and stereo system to
a commercially available audio timer as

When the preset start time is reached,
power will be switched on and playback

' will start.

Note: Be sure to set the TIMER switch to

OFF after timer-controlled recording
or playback is over. ; • '

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) ^^^v

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 batteries with the

positive (+) and negative (-) terminals
positioned correctly.

• Never use old and new batteries together.

• Replacement batteries should be of the

same type. Never use batteries of different
types together.

• 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 are 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.

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.

Troubleshooting

Notes:

• 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.

• If the decl< is operated in the vicinity of
other appliances generating infrared rays,
or if otiier remote control devices using
infrared rays are used near the V-3000,
the deck may operate incorrectly. Con­versely, if the V-3000's remote control
unit is operated in the vicinity of other
appliances which use an infrared re­mote 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 demagnetized periodically.

Cleaning Tape Path

• Apply 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 TZ-261
Tape Recorder Cleaning Kit in other
areas.

Demagnetizing Heads

Be sure that the power is off, then demag­netize the heads using a TEAC E-3 demag­netizer or equivalent. For details of its
use, read its instructions.

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 on?

DOLBY HX PRO

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 generat­ed 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 fre­quencies 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 high­frequency content of the signal increases.

>No 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?

• Unable 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 high­frequency 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 fre­quencies. The improvement is similar to
that of high-performance tape over conven­tional 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.
