What would happen if....

[thumb5]

For what it's worth I'm with Antoine on this one. The information display confirms that each individual unit knows its own serial number, date of manufacture, etc. so it must presumably have some unique factory-programmed, non-volatile memory. It would be very straightforward, and very sensible, for the firmware to query the unit type from that information and (I expect) just refuse to load a configuration file that didn't contain a matching unit type. That would also mean nothing untoward is likely to happen, so no reason not to try it if you're curious.
