5. Select Enable in the section Azimuth calibration (active satellite profile).
6. Click Apply.
7. Switch on the modem.
Azimuth calibration (user controlled)
To make a user-controlled azimuth calibration, do as follows:
1. On the page SERVICE > Calibration, select User defined in the Satellite drop down
list.
2. Type in the longitude and polarisation skew of the satellite. The polarisation skew is
provided by the satellite operator, it is typically 0 degrees. For satellite data see DVB-S
satellites on page E-1, www.lyngsat.com.
3. Select the polarisation of a transponder and type in its frequency and symbol rate.
4. Select which satellite identifier to use for identification of the signal.

5. Click Start and wait typically 5 minutes for the 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.
Check that the satellite transponder is visible from the location of the installation
and that it is at an elevation angle between 10 and 70 degrees.
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.

identifier
NID value Description
NID 0 Satellite identifier is not used.
NID 1–65535 Supplied NID is matched against Network ID broadcast
by the satellite.
Orbital position n.a. Supplied longitude is matched with orbital position
broadcast by satellite.
Not all service providers broadcast the orbital position.
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.
