EMI Certification

FCC Class A Certification (USA)

Warning: This equipment generates, uses, and can radiate radio frequency energy 
and, if not installed and used in accordance with the instruction manual, may cause 
interference to radio communications. It has been tested and found to comply with 
the limits for a Class A digital device pursuant to Subpart B of Part 15 of FCC Rules, 
which are designed to provide reasonable protection against such interference when 
operated in a commercial environment. Operation of this equipment in a residential 
area is likely to cause interference, in which case the user, at his own expense, will 
be required to take whatever measures are required to correct the interference.

You may use unshielded twisted-pair (UTP) for RJ-45 connections - Category 3 or 
greater for 10Mbps connections, and Category 5 for 100Mbps connections. For fiber 
optic connections, you may use 50/125 or 62.5/125 micron fiber.
