On P7250 model radios, when stealth mode is on, pressing any radio button (other
than the mic’s PTT button or the emergency button) on front panel will
immediately turn stealth mode off. For example, pressing the button on the
front panel will turn stealth mode off.
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.”
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.
