B Regulatory notices

Federal Communications Commission (FCC) 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 FCC ID on the label.

After the class of the device is determined, refer to the corresponding statement in the following sections.

FCC Class A certification

This equipment generates, uses, and may emit radio frequency energy. The equipment has been type

tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of the FCC

rules, which are designed to provide reasonable protection against such radio frequency interference.
Operation of this equipment in a residential area may cause interference, in which case the user

at the user’s own expense will be required to take whatever measures may be required to correct

the interference.
Any modifications to this device—unless approved by the manufacturer—can void the user’s authority to

operate this equipment under Part 15 of the FCC rules.

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 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.
