I do not know what to enter for the number of channels in my current lineup. Should I use 2 digits, 3 digits, or 4 digits?
This should be the maximum number of digits in your channel lineup. To determine the correct number of digits for your TV service, turn on your TV, and then tune your TV to the highest channel you receive a signal on.
Here are some guidelines based on current channel lineups from major providers. Note that this is subject to change.
