If the red LED illuminates, then perhaps the sensitivity setting is too low. There are many variables in determining
overall sensitivity: loop size, number of turns, loop lead-in, percent coverage, etc. In most cases, a sensitivity
setting of medium high is the correct setting. However, to compensate for some unusual loop geometries, this
setting may be inadequate. Adjust the sensitivity one level higher and recheck the detector for proper detection.
If the channel sensitivity is set to high and the red LED still does not come on and you have another operating
detector, swap the loops between a working detector and a failing detector. If the problem follows the loop the
loop is the problem. If it stays in the same detector, replace the detector.
