English

For the following explanations, refer to “Parts of 
the Radio” on page 11.

TURNING RADIO ON/OFF 
To turn ON the radio, rotate the On/Off/Volume 
Knob clockwise. The radio will chirp and the 
LED Indicator will briefly blink red.

To turn the radio OFF, rotate the On/Off/Volume 
Knob counterclockwise until you hear a ‘click’ 
and the radio LED Indicator turns OFF.

ADJUSTING VOLUME 
Turn the On/Off/Volume Knob clockwise to 
increase the volume, or counterclockwise to 
decrease the volume.

Do not hold the radio too close to the ear 
when the volume is high or when adjusting 
the volume

SELECTING A CHANNEL 
To select a channel, rotate the Channel 
Selector Knob and select the desired channel 
number. 

Program each channel separately. Each 
channel has its own Frequency, Interference 
Eliminator Code and Scan Settings.

TALKING AND MONITORING 
It is important to monitor for traffic before 
transmitting to avoid ‘talking over’ someone 
who is already transmitting

To monitor, long press and hold the SB1(*) 
button to access channel traffic. If no activity is 
present, you will hear ‘static’. To release, press 
SB1 again. Once channel traffic has cleared, 
proceed with your call by pressing the PTT 
button. When transmitting, the LED Indicator 
will blink red every 3 seconds.
