Federal Communications Commission Notice
Part 15 of the Federal Communications Commission (FCC) Rules and
Regulations has established Radio Frequency (RF) emission limits to provide an
interference-free radio frequency spectrum. Many electronic devices, including
computers, generate RF energy incidental to their intended function and are,
therefore, covered by these rules. These rules place computers and related
peripheral devices into two classes, A and B, depending upon their intended
installation. Class A devices are those that may reasonably be expected to be
installed in a business or commercial environment. Class B devices are those that
may reasonably be expected to be installed in a residential environment (for
example, personal computers). The FCC requires devices in both classes to bear a
label indicating the interference potential of the device as well as additional
operating instructions for the user.
The rating label on the device shows the classification (A or B) of the equipment.
Class B devices have an FCC logo or FCC ID on the label. Class A devices do not
have an FCC logo or ID on the label. After the class of the device is determined,
refer to the corresponding statement in the following sections.
Class A Equipment
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 harmful interference when the 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 instructions, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at
personal expense.
Class B Equipment
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
