Important!
- Before turning on the radio the first time, confirm that the power con-
nections have been made correctly and that a proper antenna is connected to the
antenna jack.
Switching Power ON/OFF
Turn the
VOL/PWR
knob turn on the radio. The display will become illumi-
nated.
Press the [
]/[
] button to choose the desired operating channel. A channel
name will appear on the display. If you want to select an operating channel from
a different group, press the [
]/[
] button to select the group you want
before
selecting the operating channel.
Setting the Volume
Turn the
VOL/PWR
knob clockwise to increase the volume, and counterclock-
wise to decrease it.
Transmitting
To transmit, monitor the channel and make sure it is clear.
THIS IS AN FCC REQUIRMENT!
Press the
PF
button which is programmed to the Monitor feature to listen for
channel activity.
When receiving a call, transmit only after the incoming call ends. The radio can-
not receive a call and transmit simultaneously.
Press the
PTT
switch.
If the channel is clear, the
BUSY/TX
indicator will glow red. The radio is now
transmitting. While holding in the
PTT
switch, speak across the face of the mi-
crophone in a clear and normal voice. For best transmission, hold the microphone
about 1-1/2 to 2 inches away from your mouth. Release the
PTT
switch to re-
ceive.
If the Busy Channel Lockout feature has been programmed on a channel, the
radio will not transmit when a carrier is present. Instead, the radio will generate a
continuous low-pitched tone while the
PTT
switch is pressed. Release the
PTT
switch and wait for the channel to be clear of activity.
If CTCSS or Digital Coded Squelch (DCS) Lockout has been programmed on a
channel, the radio can transmit only when there is no carrier being received or
when the carrier being received includes the correct CTCSS tone or DCS code.
