to it.
Insert the headset's
1

8
-inch (3.5-mm)
speaker plug into the transceiver's ear-
phone jack. Then insert the headset's

inch (2.5-mm) microphone plug into the
transceiver's microphone jack.
OPERATION
You can manually switch between trans-
mitting and receiving (see “PTT (Push-
To-Talk Button) Operation” on Page 4)
or use VOX to automatically transmit
when you talk, then receive when you
stop talking (see “VOX Operation”).
Caution: Never position the headset’s
cord or the control box near the trans-
ceiver's antenna. If the cord or the con-
trol box is too close to the antenna, the
transmitting range might be shortened
or the control box might not correctly
switch between transmit and receive.
VOX Operation
1. Set the headset’s volume control
(on the control box) to its lowest set-
ting (toward the narrow end of the
arrow).
2. Set
AUDIO/BOTH/RADIO
to
RADIO
or
BOTH
.
3. Set
VOX
to
LO
(low) or
HI
(high). If
you are operating the transceiver
where there is little background
noise, set the switch to
HI
. When
background noise or wind is strong,
set the switch to
LO
.
4. Turn on your transceiver and set its
volume to about mid-range.
5. Adjust the headset’s volume control
to a comfortable level.
6. Speak into the microphone. The
transceiver automatically switches
to transmit. When you stop talking,
the transceiver automatically switch-
es to receive after about 2 seconds.
Note: If you set the switch to
LO
,
you might have to speak in a louder-
than-normal voice.
7. When you finish operation, turn off
the transceiver first, then turn off the
headset by setting
VOX
to
OFF
.
Notes:
• The headset quickly switches the
transceiver to transmit after you
start talking. However, some trans-
ceivers require more time between
when the transmit circuit is activated
and when it actually begins to trans-
mit. On these transceivers, the first
part of the first word you say might
not transmit. You might want to pre-
cede your transmission with “Umm,”
or extend the first sound to ensure
your entire message is received.
