133. y the signal strength of the same transmitter in the same housing with the same receiver at 10 ft 3 m should be the same If not it may indicate interference or a bad transmitter Any variation in signal strength will affect receiver calibration and result in erroneous depth distance readings gt Pitch Roll Updates Verify that the squiggle in the top left window flashes every 2 5 seconds This squiggle indicates that pitch roll updates are being sent from the transmitter and heard by the receiver lf the squiggle is not appearing consistently then you should not rely on the pitch roll readings As the maximum distance range is reached the updates will become less frequent To determine whether or not a transmitter is sending adequate updates place the receiver 20 ft 6 m from the transmitter in the housing and count the number of squiggles in a 30 second period If there are six or more squiggles then adequate transmitter signal is being received by the receiver If not check for interference verify the transmitter s signal strength or call DCI Customer Service at 425 251 0559 or 800 288 3610 for assistance in determining the source of the problem gt Roll Clock Check Verify each clock position by slowly rotating the transmitter on a flat surface gt Pitch Inclination Check Confirm that the pitch readings change by moving the transmitter from positive to negative pitches inclinations DigiTrak Mark Ill Operat
