IR signals travel only short distances (40 feet or less),
and can’t go through walls or other solid objects.

UHF signals travel long distances (100 feet or more) and can
go through walls and other solid objects. Because UHF signals
travel so far, the receiver may respond to signals from other
nearby remote controls. To handle this problem, see Change the

the remote sends both IR and UHF signals to the receiver.
