Brian,
You hit the nail on the head when you stated "uses RF in some way to heat,
melt,
or spark erode" to describe Group 2 devices. That's the main distinction. In
Group 1 devices the RF is used for the internal functioning of the equipment
itself (clock signals). In Group 2 devices, the RF is used to affect a material.
Hope this helps,
Paul Boudreau
