ELECTROMAGNETIC COMPATIBILITY INFORMATION
Classes
Various national agencies (in the United States, The Federal Communications Commission (FCC) govern the levels of electromagnetic
emissions from digital devices. Electromagnetic emissions can interfere with radio and television transmission. To reduce the risk of
harmful interference these agencies have established requirements for manufacturers of digital devices
The manufacturer of a digital device must test and label a product to inform an end-user of the maximum emission level from the product
when used in accordance with its instructions. The emission levels encountered are classified as Class A or Class B. A system that
meets the Class A requirement can be marketed for use in an industrial or a commercial area. A system that meets the more stringent
Class B requirement can be marketed for use in a residential area in addition to an industrial or a commercial area.
The end user is generally held responsible for ensuring that his system is suitable for its environment as stated in the above paragraph and
bears the financial responsibility for correcting any harmful interference.
Modifications
Modifications or changes made to this device, and not approved by 3Com, may void the authority granted by the FCC, or other such
agency, to operate this equipment.
