Crunch 217B [28/36] Radar operation

RADAR OPERATION

Power & Volume control

Plug the adapter of the provided 12V DC power cord into

the lighter of your vehicle, and plug the small connector at

the other end of the 12V DC power cord into the power jack

of your detector. This will send power to the detector when

your vehicle is running. To turn on the detector, rotate the

wheel controller (located on the side of the detector) until

you hear it click. To turn off the detector, rotate the wheel

controller in the opposite direction until it clicks again. You

can also use the controller to adjust the volume level by

turning it up or down within the range that it does not click.

Brightness Control

Press DIM repeatedly to toggle between 4 different display

brightness levels: BRIGHT - DIM - DIMMER - DARK

When signals are detected, alerts are always displayed in

BRIGHT mode.

The display returns to the previously selected brightness

level after alerts disappear.

Mute on/off selection (mute mode)

Press the MUTE button repeatedly for less than two

seconds each time to toggle between mute on and mute

off.

Mute on will silence the audio alarm for the remainder of

an existing signal and for any new alert received within 30

seconds of the last signal. Then the unit automatically

resets itself to mute off, so the next signal threat can be

received. Mute off manually restores the audio alert.

You may also adjust the audio level by using the volume

thumb wheel.
