15. Appendix Antenna Configuration and Software Update

The millimetre accurate alignment of the antenna on the satellite is the
precondition for reception. The help function “Calculate Antenna Setting” is
provided to help you align the antenna. The result of the calculations is the exact
elevation angle and angle of direction.
Procedure:
Open the “Antenna Configuration” menu and press the red button. Select the menu
item “Calculate Antenna Setting”.
1. At first, select the desired satellite (e.g. Astra 19.2° east)
2. Enter the degree of longitude of your city (e.g. Hamburg 9.6° east)
3. Enter the degree of latitude of your city (e.g. Hamburg 53.3° north). The values
for the degree of longitude and latitude can be found in every good atlas.
4. Subsequently select “Calculate”. The result is the value for the elevation angle
and angle of direction.
Elevation angle: SAT antennas have a scale behind the reflector (“mirror”) which
usually ranges from 20° to 50°. In northern Germany the elevation values are
approx. 28°, in southern Germany 35°.
Note: The antenna mast has to be absolutely vertical!
Angle of direction: The degree graduation can be found on a compass.
Note: Compasses often display incorrect readings due to external influences
(metal objects and magnetic fields).
Software Upgrade
In order to add new features or to carry out error corrections, we offer the
possibility, if required, to load new software into the receiver via the ASTRA
position 19.2° east.
Note: The software is transmitted on a weekly or daily rotation for other Skymaster
models. Please refer to our website at www.skymaster.de for further information!
After the start of the OTA software update a check is carried out to determine
whether a more recent version is being transmitted. Software loading takes several
minutes. Do not switch off the receiver during the loading process! Follow the
instructions on the screen.
Note: During the process you will be asked whether you wish to retain the receiver
settings.
“GOOD” appears after the update on the receiver's display. Switch the device off
and on again via the power switch at the rear.
