TROUBLESHOOTINGS

In some region, the digital terrestrial signal may be weak.

So you’d better use the antenna in which the booster was built, for watching the weak signal channels.

You can download and upgrade the system software of the receiver through a specific channel through a specific channel designated by the broadcaster. The Distributor will provide you with more information about that.
