TALKING AND MONITORING 
It is important to monitor traffic before

over” someone who is already transmitting. 

The monitoring feature is pre-configured on 
the SB1 button.

To start monitoring and talking:

Press and hold the SB1 button to access 

channel traffic. If no activity is present, the radio 
emits a static noise.

Press the SB1 button again to release. 

Once channel traffic has cleared, press the PTT 

button to talk. When transmitting, the radio LED 
blinks red.

Select a channel by pressing the toggle buttons 

/

 

until you reach the desired channel. 

Make sure the PTT button is released and listen 

for voice activity.

The LED indicator blinks RED while your radio 

is receiving.

To respond, hold the radio vertically 1 to 2 

inches (2.5 to 5 cm) from your mouth. Press the 
PTT button to talk; release it to listen.

SCAN
The scan mode allows the radio to move 
through the channel scan list looking for eligible 
transmission activity to receive or to un mute 
to. The scanning feature is pre configured in 
the SB2.
To toggle scanning on/off:

Short press the SB2 button. When a 

transmission is detected, the radio stops 
scanning and stays on the active channel.
