8.18 ADJUST SIDE TONE AUDIO LEVEL
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.”

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.

completely off, use the “Off” setting.
