Preliminary Steps
Before operating the transceiver for the first time:
¦
Charge the battery pack and connect the supplied helical rubber
flex antenna to the antenna jack on the top of the transceiver.
Never
operate the transceiver without an antenna connected
.
¦
If you have a Speaker/Mic, we suggest you do not connect it until
you are familiar with basic operation.
¦
Before proceeding, please review the “
Top & Side Panel Controls
”
outline, if you have not already, to familiarize yourself with the
functions of the controls.
Basic Operation
r
Switch on the transceiver by rotating the
VOL
control clockwise
out of the click-stop (a momentary beep will sound). For now, ad-
just the control to about mid-position (12-o’clock), later you can
adjust the level to suit the operating environment.
r
Switch the
A/B
toggle switch to select the channel group “
A
” or “
B
”
for operation, then rotate the
CH
knob to select a channel for opera-
tion, the LCD will show the currently selected channel. If
“
----
” is displayed, along with a rapid (2 beeps/sec.) beeping tone,
the selected channel position is not available for operation.
r
To transmit, wait until the channel is clear (“
BUSY/TX
” LED off),
then press in the
PTT
switch on the side of the transceiver while
speaking across the face of the radio. A clear normal voice will
provide the best quality transmission. For maximum battery life,
select low power output (covered later) whenever possible. During
transmission the “
BUSY/TX
” indicator glows red. Release the
PTT
switch to receive.
r
To receive weak stations better, try positioning the radio as high
and far away from your body as possible, or disable the squelch
momentarily by holding the
MON RES
button on the side of the
radio for > 4 sec. (until the second low/high beep sounds). With the
squelch disabled, the “
BUSY/TX
” indicator will blinks green and
channel noise and weak stations can be heard. To quiet the radio
again, press the
MON RES
button again momentarily.
r
When you are done operating, be certain to turn the
VOL
control to
the off position to conserve battery life.
