Advanced Radio Functions

Your radio includes several advanced features that can be activated using the channel up/down keys. These functions are triggered with a long press, which means holding the button(s) for more than two seconds. 
 Channel Lock The Channel Lock feature prevents accidental changes to your selected channel. 
 
 
 To activate Channel Lock , press and hold both the UP and DOWN buttons together for more than two seconds. (You will hear a single “beep” , indicating that the channel lock is active) 
 To deactivate Channel Lock , repeat the same action. (A double “beep” will confirm that the channel is unlocked) 
 
 
 Monitor Function The Monitor Function temporarily disables the squelch, a feature that blocks background static or weak signals when no transmission is detected. 
 
 To enable monitoring , press and hold the UP (+) key. 
 This will allow you to hear all signals, including weak ones that wouldn’t normally pass the squelch filter. 
 

 To disable monitoring , release the button.
