- 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
Press and hold in the
(
POWER
) button for 2 seconds to turn the radio on.
The display will become illuminated.
Press the [
T
]/[
S
] 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 PF (Programmable Function) button which is pro-
grammed to the Group Up/Down feature to select the group you want before
selecting the operating channel. See page 7 for more information on the Pro-
grammable Function keys.
Setting the Volume
Turn the

knob clockwise to increase the volume, and counterclockwise 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
cannot 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 micro-
phone 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 receive.
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 short beep three times and indicate “

” on the display. 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.
