3. Type in its tracking frequency, 19.707 GHz.
4. Select Satellite identifier: GSC.
5. Click Start and wait typically 5 minutes for the azimuth calibration to finish. A
progress bar is shown during calibration and a message is displayed when the
calibration has completed. In case of failure, see the table in the following section for a
description of error codes during calibration.

The calibration function is not able to verify the correctness or precision
of the supplied longitude. It is therefore important to supply the correct
longitude including the first decimal.
It is strongly recommended to verify the result of a calibration
performed with user defined data. This can be done by making a new
calibration on a different satellite and verify that the resulting Azimuth
calibration value differs less than one degree.
The elevation of the selected satellite is too low. Select another satellite.
The elevation of the selected satellite is too high. Select another satellite.
The calibration values could not be saved. Possibly due to defective
hardware.
The antenna could not point with sufficient precision. Check that the
antenna is mounted in a stable way. Other possible causes might be
electrical or mechanical faults.
No signal received. Check that there is free line of sight. Try again or try
with another satellite.
RF setup error, e.g. missing or invalid TX frequency.
Invalid satellite, e.g. satellite not visible.
Unknown error
