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 op-
erate 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
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.
Rotate the CH knob to select a channel for operation, the LCD will
show the currently selected channel. If "- - - - - - - - - - - - - - - - - - - - " is displayed, along
with a rapid (2 beeps/sec.) beeping tone, the selected channel posi-
tion is not available for operation.
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 pro-
vide the best quality transmission. For maximum battery life, select
low power output (covered later) whenever possible. During trans-
mission the "BUSY/TX" indicator glows red. Release the PTT
switch to receive.
To receive weak stations better, try positioning the radio as high and
far away from your body as possible, or disable the squelch mo-
mentarily 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.
When you are done operating, be certain to turn the VOL control to
the off position to conserve battery life.
