Power On-Volume

until you hear a click and the self test "alert" tone.
Transmit
CAUTION
OPERATION OF THE TRANSMITTER WITHOUT
A PROPER ANTENNA INSTALLED MAY RESULT IN
PERMANENT DAMAGE TO THE RADIO
1) Press the monitor button to monitor the channel for activity. To
avoid interrupting another user, make sure the channel is clear
before you begin transmitting.
NOTE: Federal Communications Commission Rules and Regulations
require that you monitor a channel for activity before transmitting.
NOTE: The tri-color LED located on the top panel can help with
channel monitoring. It will glow amber if RF activity is present; or
green if the transmission has a CTCSS or DCS tone that matches a
tone programmed for receive in your radio. When this LED is not
illuminated, the radio is indicating a "clear" channel.
2) When the channel is clear, hold the radio upright with the antenna
vertical and the front microphone area about 2-3 inches from the
mouth, keeping the antenna away from the face and eyes. Press and
hold the P-T-T bar on the side of the radio, and speak slowly and
clearly into the microphone area.
NOTE: The LED will glow red when transmitting. This indicator should
be on continuously while the P-T-T bar is being pressed and the radio
is transmitting. Should the red LED be "flashing", the battery needs to
be recharged and transmission will cease. Recharge the battery before
attempting more than one transmission.
Receive
When you have finished transmitting, release the P-T-T bar to receive.
