Electromagnetic Compatibility 
International .................................................... IEC 61326-1:Portable Electromagnetic Environment; IEC 61326-2-2 
CISPR 11: Group 1, Class A 
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. 
Korea (KCC) ................................................... Class A Equipment (Industrial Broadcasting & Communication 
Equipment) 
Class A: Equipment meets requirements for industrial electromagnetic 
wave equipment and the seller or user should take notice of it. This 
equipment is intended for use in business environments and not to be 
used in homes. 
USA (FCC) ...................................................... 47 CFR 15 subpart B. This product is considered an exempt device per 
clause 15.103.
