Changing Satellites

The left and right arrow keys switch to the next east or west satellite visible to the selected LNB.
If the LNB polarity can be switched (dual polarity LNBF), the first priority id transponder will be
used and the polarity may switch if needed. If the polarity cannot be switched (single polarity
LNB with dedicated feed horn for VSAT or commercial TVRO applications), the selected polarity
will be maintained.
If you have selected a multi-LNB system, the selected satellite will also change when you use the
LNB soft-key to switch between LNBs. (See Multi-LNB Systems below.)

Changing Transponders

The up and down arrow keys take you to the next or previous transponder in the same satellite
(actually in the same orbital slot). If the polarity is locked (via single polarity LNB type) then you
get the next transponder of the selected polarity. Only transponders visible to your region are
used.
Polarity
If the LNB supports polarity switching (i.e. dual polarity LNBF) or is stacked, the polarity key is
disabled (as shown above) and the transponder selection determines the polarity.
If you are using a single polarity LNB, the polarity must be selected (to match the orientation of
your feed horn) using the polarity key (top right soft-key) and the transponder selection is limited
to the selected polarity. See figure below.
