Scan option reference
This reference covers form variants in the reviewed revision. Hardware and selection determine which subset is shown. Identically named fields can appear in different places. Technical expressions are source-code search aids, not commands to paste into the receiver. nim denotes a tuner, currLnb the selected LNB profile, and Sat a satellite assignment.
