International ................................................................ IEC 61326-1: Portable Electromagnetic Environment 
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. 
Caution: This equipment is not intended for use in residential environments and may not provide adequate 
protection to radio reception in such environments. 
Emissions that exceed the levels required by CISPR 11 can occur when the equipment is connected to a test 
object. 
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.
