How does the eToll Clip work?
Just Clip it and Stick it! – All three suction cups are installed into the eToll Clip prior to shipping. The toll transponder is then clipped into the eToll Clip with the LED’s and battery cover facing toward the open end of the clip. Once the transponder is installed in the clip, it is ready to be secured to the interior windshield of the vehicle. The suction cups should be moistened prior to applying them to a cleaned windshield. The eToll Clip can then be repositioned as desired. For more information please see the supplied instruction pamphlet.
