The RoboToolz RT-7690-2 receiver may not be showing levels because the RF Remote/Detector has been activated but the lasers have not been turned on. After activating the detector, you must turn on the level and/or plumb laser for the detector to display level information. If the lasers are off, the detector will not show level data.
