released within two seconds the monitor function will deactivate
when released. If the upper function button is held pressed for
more than two seconds the monitor function will latch on. Press

When the monitor function is turned off a low pitched
beep will sound and the status LED will turn off.

The upper function button is also used to mute the radio

hold the upper function button for more than two
seconds to mute the radio until the next 2-tone or
selective call.
Transmitting to other radios
Follow these steps to transmit on your radio:
1. Make sure that the channel is not busy (transmitting while
another radio is transmitting will only create interference,
please wait for the channel to clear).
2. Press and hold the PTT button. The status LED will glow
red.
3. Talk in a normal voice with the microphone approximately 2-
4 inches (5-10 cm) from your mouth. When finished
speaking, release the PTT button.

Do not shout! It will only create distortion.

Press PTT before you start talking and release PTT after
you have finished speaking.

Your radio doesn’t allow you to talk and receive
simultaneously, so keep your transmission short. When
you are transmitting, other people can not. Use common
sense and do not occupy the channel too much.
