If not use the remote-controller with data formats recommended, IR output signals will be suppressed
automatically by IR receiver. In this case, LG does not guarantee IR working function. To make sure of this
matter, here are two methods as below.
• Use the remote-controller with suitable data formats.
• Use the IR dongle receiver of the set-top box.
