3 Scanning for Channels
A broadcast satellite’s channels are called transponders. A transponder gath-
ers signals over a range of uplink frequencies and retransmits them on a differ-
ent set of downlink frequencies to receivers on Earth. Multiple TV channels are
broadcast through a transponder. A transponder has three main components:
frequency, symbol rate, and polarization.
3.1 Satellite Dish Settings
LNB Settings
A group of satellite dish settings must be properly configured for each desired
satellite before performing a channel scan.
Open the Settings > Installation > Dish Setting menu. There are two signal
bars on the lower part of the screen. The signal level bar indicates how strong
the signal is, and the signal quality bar indicates how easy it is to pick up. To view
an enlarged signal bar display, press the blue button.
Configure the following settings properly using the signal bars.
• Satellite: Choose a target satellite from the list of satellites.
• Frequency: Choose a target transponder from the list of transponders.
• LNB Power: An LNB must be supplied with power to operate. Turn this on
to supply the LNB with power if it doesn’t have its own power supply.
• LNB Type: Specify what type of LNB is used.
• LNB Frequency: Specify what frequency the LNB generates. A dual-band
LNB, also called universal LNB, generates two alternative frequencies to re-
ceive a wider band of satellite frequencies.
• LNB 22 kHz: Either turn this on or off to pick up a higher or lower frequency
band.
