Ah I see. That timeout is when the TV signal will be cut off. Set it to four hours and if the picture does go off, just turn the Horizon box on again. It’ll come back on immediately from HIGH mode.
The 4 hours is only if you don’t send the horizon box any commands, such as changing a channel. So if you watch one channel for a long time then yes, it probably turns off. I’ve never noticed it! Just going to check my settings …
Interesting - the Auto Standby setting has no “OFF” any more. It’s confusing. Mine is set to Auto, the Define Auto Standby Time seems to be from 23:00 to 05:00 (although I’ve never known my box turn off at 11pm) and Activate Standby After is set to 240.
My Standby Power Usage is set to Eco though, as I use the Connect Box for internet and landline.
It’s confusing.
