The reference satellite is another search option that could be utilized by the user. The controller
will lock onto the Reference satellite DVB carrier, and will pivot to the target satellite position to
peak on the modem signal. Users acquiring Satellite using RF Search or direct DVB search with
the Target satellite DO NOT require this option.
