Repeat this action to change to another frequency. You can use the Õ/Œarrow buttons to change between low and high resolution. When displaying high resolu- tion (i.e., least significant digits), the decimal point flashes ON and OFF repeatedly. The Local Oscillator #2 frequency can be displayed from any channel, but can only be changed from the Installer Channel (see “…About the current channel”). The Local Oscillator #2 frequency is associated with the L-Band 2 [Lb2] and Downlink (dnLn) Frequency Mode, and is required if you are using a dual Ku-Band LNB system. If used, the Local Oscillator #2 frequency must be higher than the Local Oscillator #1 frequency. For more information about frequency settings, see “Setting up the receiver”.

Repeat this action to change the Polarization. The Polarization can be displayed from any channel, but can only be changed from the Installer Channel (see “…About the current channel”). When a Horizontal polarization is set, a 19 volt DC signal is output via the receiver rear panel SATELLITE connector. When a Ver- tical polarization is set, a 13 volt DC signal is output via this connector. If a fixed Horizontal or Vertical polarization is set, the setting cannot be changed via uplink control. Observe the effect of the Polarization change by checking the displayed relative Signal Strength value (see “Signal Strength“). Higher Signal Strength num- bers are better.

The Search option is an Alt-2 mode function. Searching for a signal with the Search option is used for restoring normal receiver operation if the received signal is inter- rupted or lost, or is changed by the local broadcast satellite services provider.

A signal search is enabled by setting the Search option to ON, and disabled by set- ting this option to OFF. When enabled, a signal search is activated automatically only if the carrier signal is interrupted or lost for more than 20 seconds (normal operating mode only). For more information about Signal Searches, see “Setting up the receiver”.
