Absolute Value increases the detectionarea of these loops in the non-discriminate modesto their entire length. Use of Absolute Value is notrecommended for round-loop designs.ABSOLUTE VALUEONOFFTO CHANGE PRESS ENTERTips - Turn ON if elon-gatedBigfoot orGoldfootloops (differentiatingdesigns) have beeninstalled.6. ModulationAllows motion modes to produce different volumelevels based on target depth.Modulation is used in the discriminate or motionmodes. When ON, it allows the depth of the targetto dictate the volume of the response. Thus deeptargets can be easily recognized by their lower-volume sound. If OFF, the discriminate or motionmodes will produce the same volume of responseon all detected targets regardless of depth. The useof MODULATION allows for the singling out ofdeep targets in the standard discriminate mode. Itsaves time by eliminating the checking of eachtarget with the depth indication in the pinpointmode.MODULATIONONOFFTO CHANGE PRESS ENTERTips - If you have excellenthearing and want to singleout deep targets by theirlower-volume responses,use modulation. ON is thedefault (standard setting)for all factory PresetPrograms. If your hearingisn't the best, the OFFsetting is recommended.(Audio section)(Audio section)
