IEC 61326-2-2 
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. 
Emissions that exceed the levels required by CISPR 11 can occur 
when the equipment is connected to a test object. The equipment 
may not meet the immunity requirements of this standard when test 
leads and/or test probes are connected.
