ENGLISH ENGLISH
Objects such as trees, bridges and large houses located at the satellite‘s angle of in-
cidence cause the signal to be lost. Heavy rain, clouds, snow or ice can affect the recep-
tion quality. If the satellite signal is lost due to severe weather conditions, the current
program of the receiver will be stopped (the image will freeze or disappear). When the
weather conditions allow good reception again, the TV picture will be restored.
Signals in vertical (red) and horizontal (blue) lines have an offset of exactly 90º to each
other. Due to the different positions of the satellites, depending on your location, it is
possible that the signals do not hit the LNB exactly vertically and horizontally. To adjust
this, you must place the LNB in the correct position to the transmitted signal. This
adjustment to the LNB is called a „skew setting“. The following figure shows the optimal
adjustment of the LNB. The better the match, the better the reception.
If you are in Central Europe, no skew settings are usually necessary. To adjust the skew
setting, proceed as follows:
