Note: 

1. Make sure the radio is switched off during charging or the charging time will be 
longer and number of possible battery charge cycles reduced. 
2. Li-ion batteries do not have memory so they can be recharged at any time. There 
are a limited number of charge cycles that the battery can handle, typically 500-700 
times. To get the maximum use of the battery, only recharge when getting flat. If an 
almost full battery is recharged, the charging cycles are not optimized. 

 

 

Basic Operation 

Power On/Off 

Turn the Power Knob clockwise to switch on th

e radio; you will hear “TURN ON THE 

RADIO” and current channel number voice message. Turn counter-clockwise to 
switch off the radio.   
 

Adjust the Volume 

 
Hold in the side 

“Monitor” or “Squelch Off” button to listen the background noise, then 

turn the On/Off knob to increase or decrease the volume.   

 
Select a Channel   

Turn the Channel Selector Knob clockwise to change the channels from 1 to 16. Your 
radio will report the channel number.   
Refer to the factory channel settings when linking your radio to other radios as it may 
be necessary to reprogram or adjust the frequency / sub tone to match. 
 

Transmit   

Keep pressing down the PTT key and speak directly into the microphone hole (MIC). 
Hold the radio about 2.5cm to 5cm from your mouth. The radio should be held so that 
the antenna is vertical. Speak slowly loud and clear into the radio for a good signal to 
be received. 
 

Receive 

Release the PTT key to receive a call and adjust the volume if needed. 
 

Monitor   

The  squelch  circuit  in  the  transceiver  mutes  the  speaker  automatically,  when  no 
signals are present so you will not hear background noise. Hold in the side button to 
monitor  a  frequency  by  deactivating  the  squelch.  This  is  useful  when  you  want  to 
adjust the volume level, or when you need to hear a weak signal.
