I have a 505 and the trip count was at 76 so I reset the receiver and a few days later it is at 3...what's up. Should I be concerned oe how to fix? (I thought it should be at zero...have had this for couple of years now so not an avtivation thing)

Thanks

They send program changes out, like in April the Fight Network is on freeview, when they do this the trip count goes up, there is nothing to worry about.
