I installed it in the motorhome and not permanently, as I used it at different points.
Set it up, briefly align it with the screen and start it up. The start-up and automatic alignment
takes about 10 seconds as already mentioned and then it is ready for use (if Internet / hotspot is set up)
The only setting I have to make is the scaling, as I don't always have the same distance and screen size.
But even that is set very quickly.

It takes approx. 10 seconds to start up and aligns itself during this time.
