STEALTH MODE  
For some users, it is important to be able to turn off the radio’s display lights and side tones, but not the 
radio traffic. For example, in covert operations, lights and sounds could inadvertently expose an otherwise 
unobservable radio user. For this purpose, the radio has a Stealth feature that disables the radio display 
light, indicator light and audible side tones.  
When stealth mode is on, the radio continues to scan the programmed list of talk groups and the user can 
key-up on the selected talk group.

Enabling Stealth Mode 
Press the 
 or 
 buttons to scroll through menus until “StealthMenu” appears in the display. To 
immediately activate Stealth Mode press the   or   button once. This activates Stealth Mode, exits the 
Stealth Menu, and returns to the Dwell Display. 
The display lights, indicator lights, and side tones are disabled. The stealth mode icon is displayed.

Disabling Stealth Mode 
To re-enable all lighting, side tones and exit Stealth Mode, press any key other than PTT or Emergency. 
This returns to the Dwell Display. 
The display lights, indicator lights, and side tones are re-enabled. The stealth mode icon disappears.

Stealth Mode using A/B Switch 
It is also possible to enable and disable Stealth Mode using the A/B Switch, if so programmed.  
Depending on programming the switch in one position will enable Stealth Mode and in the other position, 
disables it. 
 
 
With stealth mode 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.

ADJUSTING 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 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.
