If problems do occur in an exhibition, then there is a very simple solution. Plug in a tethered handset(s) and use that/those instead.

Basic Dynamis is probably the only system where you can't do this, but adding the Pro Box allows tethered handsets to be used.
With IR there shouldn't be as much of a problem with the limited range available.
