Group 1: Equipment has intentionally generated and/or uses
conductively-coupled radio frequency energy that is necessary
for the internal function of the equipment itself.
Class A: Equipment is suitable for use in all establishments
other than domestic and those directly connected to a low-
voltage power supply network that supplies buildings used for
domestic purposes. There may be potential difficulties in
ensuring electromagnetic compatibility in other environments
due to conducted and radiated disturbances.
Caution: This equipment is not intended for use in residential
environments and may not provide adequate protection to radio
reception in such environments.
