CASSETTE INSERTION
Before inserting a cassette, take
up any slack in the tape by insert-
ing a pencil into the hub of the cas-
sette and turning it a few times.
Press the STOP/EJECT key to
open the cassette door. Insert the
cassette into the chamber with the
exposed edge of the tape facing
you and the full reel to your left.
Close the door by pressing down-
ward until it latches shut.
To remove a cassette, press the
STOP/EJECT button once to stop
the recorder. Press the button a
second time to open the cassette
door.

RECORDING WITH BUILT-IN
MICROPHONE
MICROPHONE
Insert a tape and simultaneously
depress both the RECORD and
PLAY keys. The tape will begin
to move, and the machine will be
recording. The recorder will continue
to record as long as there is suffi-
cient audio in the amplifier to trigger
the voice-activation circuit.
It stops after it is quiet for a few
seconds and starts recording when
you speak within a few feet of the
microphone.
The volume control is inoperative
in the record mode. The MONITOR
function should be off (MONITOR
key UP) to prevent feedback during
microphone recording. To end the
recording, depress the STOP/
EJECT key. Depress this key a
second time to EJECT the cas-
sette. If you reach the end of the
tape while recording, the recorder
will shut off and the PLAY and
RECORD buttons will pop up.

Plug a suitable microphone
(such as the OMNICRON RMC-8 or
PZ-2LA) into the MIC or MIC and
REM jacks on the left side of the
recorder. The large jack (MIC) is the
microphone circuit. It is also used

REM jacks on the left side of the
recorder. The large jack (MIC) is the
microphone circuit. It is also used
to connect other low level audio
sources to the recorder.
The small jack next to the MIC
jack is the remote switch circuit
(REM). When the remote jack is
used, the tape will not move in the
RECORD mode unless the external
remote switching circuit is on. The
voice activation circuit also must
have sufficient audio to start the
motor. Operate the recorder as de-
scribed in the instructions for built-
in microphone recording.

RECORDING FROM OTHER

SOURCES: RADIO, PHONE,
ETC.
Your recorder receives audio ei-
ther by placing a microphone near
the speaker of your audio source, or
by connecting directly
to the speaker or audio output of
the device you wish to monitor. If
possible, use a direct connection
to prevent unnecessary noise
pickup. A direct connection also will
produce clearer recordings.
Most telephone and some two-
way radio installations require the
use of an interface coupler or
adapter (such as the TSA-3,
LIC-390, or LIC-100) between
the recorder and the audio circuit.
Couplers provide isolation and
a balanced line input. They also
help to prevent the noise on tele-
phone lines from reaching the
recorder between conversations.
Check with your Omnicron dealer or
telephone company to see if you
require a coupler for your applica-
tion. Do not connect the recorder
directly to telephone lines without
a coupler. Improper operation of
both your recorder and the tele-
phone circuit could result. The re-
corder could also be damaged.
An accessory patch cord is avail-
able (AUX-6S) for use if you will be
connecting the recorder to your au-
dio source without a coupler. It has
a miniature phone plug on one end
to match the auxiliary

to match the auxiliary
audio input jack on the recorder

shorten or lengthen it if necessary.
The spade lugs can be changed, if
required, to match the audio con-
nections on your signal source
(two-way radio, tone alert receiver,
scanner, tape recorder, pocket
pager, etc.). The cable may be
special ordered to match your
specific application.

VOICE ACTIVATION
SENSITIVITY
SENSITIVITY
If the recorder does not record
weak conversations properly after
adjusting the RECORD LEVEL, you
can adjust the recorder so it will be
more sensitive and start recording
with weaker sound levels by turning
the ACTIVATE SENSITIVITY control
clockwise. You will find this screw
driver adjustment on the bottom of
the recorder. You can also adjust
this control to make the recorder
less sensitive if it runs with noise
that is weaker than the normal con-
versation level. To make the voice
activation less sensitive, turn the
control counter-clockwise with a
small screwdriver.
Adjusting the ACTIVATE SEN-
SITIVITY control too far in the
clockwise direction can turn off the
voice activation circuit. This will
cause the unit to run continuously
when it is in the record mode.
Adjusting the control too far in the
counter-clockwise direction will
cause the recorder to remain
stopped in the record mode even
if there are loud sounds in the am-
plifier. DO NOT FORCE THE
CONTROL.
Since the sensitivity of the voice
activation circuit is also affected
by the setting of the record level
adjustment, you should adjust the
record level for best sound quality.
Then adjust the ACTIVATE SEN-
SITIVITY if necessary to insure that
the recorder does not run when it
should be stopped, or if it stops
when it should be recording.
