The radio sounds confirming tones called “side tones” when its buttons are pressed. Most users find this 
audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned 
completely off using the “Side Menu.” 

For covert operations, it may be necessary to turn off side tones. For safety’s sake, turning off the radio 
during covert operations is not recommended. 

If the radio is operating properly but side tones are not heard when the menu buttons are pressed, the side 
tones are probably turned off. To turn them back on, access the “Side Tone” menu and select a setting 
other than “off.” 

Use the following procedure to set side tone level: 

1.  Press the 

 or 

 buttons to cycle through the menu until “Side Menu” is displayed. 

2.  Press 

 or 

 to change to the desired level (Off, Low, Medium, and High). To turn side tones 

completely off, use the “Off” setting.
