HOW TO MOUNT AND INSTALL THE AV-1KM
Fasten the doose neck boom (3) under the car sun viso by using the car’s existing screw or bolt.
We recommend the position to the right of the driver. Attach the wind-shield (1) to reduce the
noise.
The PTT box (8) is attached to the gear change with a rubber band (6). Observe the way the band
is formed into two fastenings.
Connect the microphone cord (4) to jack (5). Then, connect the approppiate microphone for using
your radio from the PTT box to your transceiver (It can happen that you have to tilt lightly the jack
forwards before pulling).
HOW TO USE
Set the TX/RX selector (12) to “T” for transmitting
and to “R” for receiving. The LED indicator (17)
should light up when in “T” mode. Speak about 10
cm from the microphone and adjust microphone’s
gain (11) to suit your voice and radio.

CABLE
SWITCH BOX
If your radio has the feature, the up/down buttons
(9/10) should change frequency or channel. The ac-
tual operation depends on your rasdio design.
The CALL (LLAMADA) (13), VFO (14), MEMORY RE-
TURN(15) and PRIORITY FUNCTIONS (16) have simi-
lar functions as those on your radio (subject to your
radio’s design).

ADJUSTING THE MICROPHONE GAIN
The gain control (11) is quite critical. Please, adjust it care-
fully as it is directly mounted on the circuit board. Get ano-
ther operator to listen to your radio or watch the ALC
reading in the case of SSB. Too much gain can cause dis-
tortion! FIG.4
RF FEEDBACK
If you run high power, you could have problems with RF feedback. Make sure that the microphone
cable does not run near the antenna cable and make sure the VSWR is low. If any problem per-
sist, then try placing a ferrite ring at the point where the microphone cable enters the base of the
PTT box. In the worst case, also try a ferrite ring near the point where the microphone cable enters
your transceiver. Before carrying out these suggestions, do check that there is no RF feedback
with the normal transceiver microphone. If there is, then consult your dealer.
