Xfinity is code 1014.
Make sure t use the OK/Enter function when setting Favorites. n Flipper the OK signal is in our Mute button.
The channel format is: 1-2-3-Mute-ADD; 4-5-6-Mute-ADD; etc.
Older models of Flipper (V3 and below) d not have this functionality. Only recourse is to upgrade to a current model. Xfinity changed their format in late 2014, and we adjusted Flipper to accommodate this in mid 2015.
