I have set up an activity with a tv, Denon amp & Beyonwiz media player which usually works. Obviously the Beyonwiz is the controlling device.

My question is, Every now & again the Denon amp doesn't power on, So how am I supposed to access the Denon remote to power on ?

As it only has power toggle, if I close down that just starts it up, so all out of sync.

2nd question is what are the led lights & the home button for, As far as I can tell they do nothing ? I cant find anything documentation explaining these

I would appreciate anyone pointing me in the right direction.

Program one of the other unused buttons on the remote with a power toggle for the Denon. You could even use a different activity button (A,B,C) if you need to.
