It's ugly head has again been shown.

Mystery drop out of communication between a 7500 and a 6500.

It works fine when I am there and when I push the buttons but.....

When I leave "everything" stops working.

I am just curious what people have discovered regarding wireless interference issues with Pronto.

Any specific sources of interference proven or suspected?

Any strange behaviors of the system due to wireless issues?

Any suspected wireless issues found not to be the issue?
