Be patient and read the manual slowly cover to cover...Some manuals can be a bit vague if you are new to the eco system.
In such instances, get on the "home theater enthusiasts" groups on FB and ask if anyone lives near you. Some nerd who lives nearby might volunteer and get you set up for free...especially if you offer some vodka with freshly squeezed (fresh fresh fresh) orange juice.
The nerds who’ve been rattling around with it for a long time may know more about some quirks than the pro installers.
