Calibration Procedure
1.
Install antenna if not already installed. Since there are no hard limit switches in the DXE-RT4500HD,
you can point the antenna at any known direction to complete the calibration. The rotator does not
need to be in the center of Rotation. Likewise, if the mast clamp or any part of the system gets out of
calibration, just point the antenna at a know heading and continue with the calibration procedure
below.
2.
Look at the current direction of the antenna and note the true heading. Then press SETUP until the
displays says “Setup”, then let go and you will be in the “Calibrate” item. Turn the knob until NEW
VALUE is equal to the current true heading. Press CHANGE, then press SAVE.
