What To Remember While Using IntelliMute

IntelliMute works with both City and Auto Mute modes.

Whenever your engine revs are below the activation point, 
the dot next to the large character on the right side of the display 
will remain lit. Above the activation point, the dot will blink twice 
every two (2) seconds.

If, for any reason, the unit stops sensing your engine’s revs, 
IntelliMute will indicate an error and automatically turn Off.

The rev point you set will be stored in the unit’s memory when 
power is turned Off and recalled each time the power is turned On.

NOTE
The rev point must be reset if you use your detector in a different vehicle.

NOTE
When initially choosing your IntelliMute activation point, a setting 
of approximately 300 to 600 RPMs above idle is recommended. 
You can reset the activation point at any time to fit your individual
preferences and driving style.

Setting The IntelliMute Activation Point

Your detector must be installed in your vehicle.

CAUTION
Do not attempt to set the rev point while driving. 
Your vehicle should be parked and idling. 

IntelliMute must be turned 

On before setting the activation point. Depending

on whether the unit is in Tone Alert or Voice Alert mode, you will hear a
series of beeps or voice messages as you follow the steps on page 11.
