Consult your dealer or communications coordinator for
further details on how your radio has been programmed
for 2-tone operation.
2-tone signaling allows users to receive only calls
intended for them. However, more than one radio
transmitting at a time will still cause interference. Do not
transmit if the Tx/Busy indicator is illuminated green or
amber. Wait until the channel is clear before transmitting.
Transmitting to Other Radios
! Before transmitting, the FCC requires you monitor
the channel to make sure it is clear. Transmitting
while someone else is transmitting will create
interference and disrupt both conversations.
Follow these steps to transmit to other radios.
1. Monitor the channel by pressing the programmed function
button. Depending on programming the monitor button may
disable 2-tone, CTCSS, DCS or noise squelch to allow you
to check for channel activity. Channel activity is also
indicated by the Tx/Busy indicator.
2. If the channel is clear, press and hold the push to talk (PTT)
switch on the side of the microphone.
3. The Tx/Busy indicator will glow red while the radio is
transmitting.
4. Hold the microphone approximately 2 inches from your
mouth and speak across the face of the microphone in a
clear, normal voice.
5. Keep the PTT switch pressed until you have finished
speaking.
6. Release the PTT switch to return to receive mode.
Do not shout! It will only create distortion.
