FCC Information
Regulations
Concerning
Electromagnetic
Radiation
The Federal Communications Commission (FCC) of the United States of America
and the Industry and Science Canada (ISC) have published regulations that govern
the allowable limits of emanation of radio frequency energy of computing devices
and associated peripherals. These regulations are concerned with interference to
radio communications, such as radio and television. The regulations require
equipment for use in the United States or Canada to be labeled and to be
accompanied by the following notice:
Correcting
Interference
If this equipment causes interference to radio or television reception, which can be
determined by turning the equipment off and on, you are encouraged to try to correct
the interference by one or more of the following measures:
• Reorienting the receiving antenna
• Relocating the equipment with respect to the receiver
• Moving the equipment away from the receiver
• Plugging the equipment into a different outlet so that the equipment and
receiver are on different circuits
If necessary, you should consult the dealer or an experienced radio/television
technician for additional circuits.
Additional
Information
You may find the following booklet prepared by the FCC helpful: How to
Identify and Resolve Radio-TV Interference Problems. This booklet is available
from the U.S. Government Printing Office, Washington, D.C. 20402,
Stock No. 004-000-00345-4.
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against interference when equipment is operated in a
commercial environment. 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.
This digital apparatus does not exceed the Class A limits for radio noise emissions
from digital apparatus set out in the radio interference regulations of the ISC.
Operation of this equipment in a residential area is likely to cause interference in
which case the user will be required to take adequate measures to correct the
interference.
This product was verified under test conditions that include use of shielded DTE
cable(s). Leased line cables with 1.5 turns through a ferrite cylinder were also used.
Use of different cables will invalidate verification and increase the risk of causing
interference to radio and TV reception.
You can obtain the proper cables from 3Com.
