This menu lets you configure and store sets of network parameters to be used to define as many as 24 network signals. Each configuration set is called a “preset” and is uniquely identified by a preset number (0 to 23).

The settings in fields Freq Mode, L.O. Freq #1, L.O. Freq #2, and Crossover can be changed only at the Receiver Setup menu. These setting are used for all network presets. If you set L.O. Freq #1 to a value less than 8 GHz, it is used as a C-Band L.O. frequency for all network presets. If you set L.O. Freq #1 to a

￿￿value greater than 8 GHz, it is used as a low Ku-Band L.O. frequency for all network presets

If you use Ku-Band, you must define L.O. Freq #1, L.O. Freq #2, and Crossover â(at the Receiver Setup menu).

If your LNB has only one local oscillator, set both L.O.s to the same local os- cillator frequency.

âWhenever you change a setting that is common to both the Receiver Setup menu and the Network Presets menu, the setting is changed accordingly in

âboth menus.

The current band you are using at the Network Presets menu depends on the frequency defined. Any frequency between 0 and 8 GHz is C-Band. Otherwise,

the frequency is KU-band.
