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.
FCC rating label
The FCC rating label on the device shows the classification (A or B) of the equipment. Class B devices have
an FCC logo or ID on the label. Class A devices do not have an FCC logo or ID on the label. After you
determine the class of the device, refer to the corresponding statement.
FCC Notice, 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.
FCC Notice, 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 equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
