New to Vero 4K+. Where is a full manual and user guide?

This is what you sent in an email when the Vero 4K arrived and the remote did not work:

  • Remove the USB from Vero 4K
  • Hold Home and OK button for 5 seconds or so, then the blue LED will keep flashing.
  • Plug in the USB receiver and the LED should flash 3 times after 5 seconds, indicating successful pairing.
  • Power off Vero 4K for 2 minutes. Turn it back on. The remote should now work.

That fixed it then but nowadays, in the times it looses its sync and I do the above instructions, when I hold the Home & OK for 5 seconds or more, the blue light never flashes, it just stays solid blue. When I plug the USB receiver back in, the blue light just keeps staying on forever. It is a case of trying all sorts of combos of USB in & out, 4K off and on and eventually, the darn thing will start working again.

Is there a way that I can force it completely out of sync so that it will go through the “blue LED will keep flashing”, etc?
