Talking about grouping failure

In the process of upgrading digital TV, the user missed pressing the "OK" key.

The specific solution is to directly unplug and reconnect the power plug of the set-top box (note that it is not the set-top box switch), and the set-top box will search the channel by itself, and it will be fine after the search.

The radio and television system has an area code lock, which can only be used in the registered area. There will be errors in other areas, and the area code cannot be modified.
