Important! - Before turning on the radio the first time, confirm that the power connec-
tions have been made correctly and that a proper antenna is connected to the antenna
jack.
Switching Power ON/OFF
Push the POWER switch turn on the radio. The display will become illuminated.
The radio will start up on the last channel used prior to shut-down during the previ-
ous operating session.
Turn the CHANNEL selector knob to choose the desired operating channel. A chan-
nel name will appear on the display. If you want to select the operating channel
from a different Memory Channel Group, press the UP (
p
) or DOWN (

) button
to select the Memory Channel Group you want before selecting the operating chan-
nel.
Setting the Volume
Turn the VOLUME knob clockwise to increase the volume, and counterclockwise to
decrease it. If no signal is present, press and hold in the MON button more than 1/2
seconds; background noise will now be heard, and you may use this to set the VOL-
UME knob for the desired audio level. Press and hold the MON button more than
1/2 seconds to quiet the noise and resume normal (quiet) monitoring.
Transmitting
To transmit, wait until the “ BUSY ” indicator is off (the channel is not in use), and
press the PTT (Push-To-Talk) switch on the side of the microphone (the “ TX ” in-
dicator will appear or the “ TX ” indicator will glow red). While holding in the PTT
switch, speak across the face of the microphone in a clear, normal voice level, and
then release the PTT switch to receive.
Selecting Groups and Channels

Press the UP (
p
) or DOWN (

) button (repeatedly, if necessary) to select a
different group of channels.

Turn the CHANNEL selector knob to select a different channel within the cur-
rent group .
Automatic Time-Out Timer
If the selected channel has been programmed for automatic time-out, you must limit
the length of each transmission. While transmitting, a beep will sound five seconds
before time-out. Another beep will sound just before the deadline; the “ TX ” indica-
tor will disappear and transmission will cease soon thereafter. To resume transmit-
ting, you must release the PTT and wait for the “penalty timer” to expire (if you
press the PTT before this timer expires, the timer restarts, and you will have to wait
another “penalty” period).
