Dig. receiver + Disc-R + Home Theatre
If you use a digital receiver to watch TV (a set top box - STB)
and you do not use the remote control of the TV, then switch
off the automatic switch off. This will prevent the TV from
switching off automatically after a 4 hour period without a key
press on the remote control of the TV.
To switch off the automatic switch off, press the green key while
you are watching TV channels and select Auto switch off and
select Off.
First, use 3 antenna cables to connect the devices to the TV.
Then use an HDMI cable to connect the digital receiver to the
TV.
