Unlike Direct TV, Dish TV has frequent updates, and there are three ways to update. If you have Dish TV, you must have the system in a position to update or you could be charged a monthly fee of up to $5.
Keep the receiver plugged into a phone line at all times. This will allow updating daily if needed by Dish TV.
Plug the receiver into the phone line at least every other day or weekly to allow the system to update.
Plug the receiver into a phone line nightly when not in use so that it can update. Use the phone line during the day for calls.
