 Your detector allows you to quickly turn Off an audio Alert by momentarily 

pressing the Mute button. If you press the Mute button a second time  

during the Alert, the audio Alert will be turned back On.

 Auto  Mute will automatically reduce the audio volume of all alerts  

after four seconds for as long as the signal is detected. The factory  

setting for Auto Mute is On.

IntelliMute is a unique feature that allows you to avoid alerts you don’t need 

to hear because you are stopped or moving slowly. By sensing the “revs” 

(RPMs) of your engine, IntelliMute knows when you are at low speed and 

automatically mutes audio radar alerts.
 Before IntelliMute will work, you must set an activation point for your engine’s 

revs (see page 10). Whenever the revs are below that point, IntelliMute will 

begin muting. The activation point will be stored in memory and recalled  

each time the power is turned On. The factory setting is IntelliMute Off.

IntelliMute may not work with some vehicles because it cannot sense 

the engine’s revs. In such cases, you can reduce unwanted audio alerts 

by using Auto Mute and City mode when appropriate.
