to your antennas either directly or via the loop-through cable.
If you have connected only one socket, you could not use some
features such as dual recording.
The digital receiver has a database about broadcasting satel-
lites and their transponders, containing the following infor-
mation: satellite position, frequency range, symbol rate, po-
larization and LNB frequency corresponding to the frequency
range. So you might not have to specify the LNB Frequency
option. However, if you have selected the Other entry at the
Satellite Name option to specify a satellite that is not in the
satellite list, you might have to make out the correct LNB fre-
quency. The difference between a broadcasting frequency and
its LNB frequency must be within 950 to 2150 MHz. For exam-
ple, if the frequency band of your desired satellite ranges from
3660 to 4118 MHz, you have to set the LNB Frequency option
to 5150 MHz.
The LNB has to be supplied with power to operate. Set the
LNB Power option to On if it does not have any other power
supply.
You had better ignore the 22 kHz option.
The digital receiver is designed to be compatible with DiSEqC
(Digital Satellite Equipment Control) switches. It is possible
to connect several antennas to one digital receiver by DiSEqC
switches. A DiSEqC 1.0 switch allows switching between up
to 4 satellite sources and a DiSEqc 1.1 switch allows switching
between up to 16 satellite sources.
Set the DiSEqC 1.0 and DiSEqC 1.1 options according to your
antenna configuration.
