disposed of with household refuse. Please obtain appropriate information about the

regulations in your community, and dispose of all refuse in accordance with regulations

at the separate locations provided.

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.
