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
 
   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. 
 
RECORDING WITH 
EXTERNAL  
MICROPHONE 
  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 
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.  
Increase or decrease the record 
level as necessary. 
 
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  
 
audio input jack on the recorder 
(AUX) and spade lugs on the other 
end. It is six feet long. You can 
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 
   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.
