Free to air channels do not need special inputs in a wiztech besides you making sure your your dish is well positioned and you go through the setup procedure of re-scanning. While your question is a little ambiguous, the only time you need to input something related to channels, is when you need to unscramble locked channels which then becomes an ethical matter. For this I believe its best you have a one to one talk with your installer as not many people may want to be associated with piracy. Apologies if I did not get your question right.
