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 (i.e., 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 which class (A or B) the equipment falls into. Class B devices have
an FCC ID on the label. Class A devices do not have an FCC ID on the label. Once the class of the device
is determined, refer to the following corresponding statement.
NOTE: If this equipment contains a Token Ring interface, this equipment is a
Class A digital device when the Token Ring interface is utilized.
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.
Canadian Notice
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment
Regulations.
Avis Canadien
Cet appareil numérique de la classe A respecte toutes les exigences du Règlement sur le matériel
brouilleur du Canada.

Modifications
The FCC requires the user to be notified that any changes or modifications made to this device that are
not expressly approved by Compaq Computer Corporation may void the user's authority to operate the
equipment.
Cables
Connections to this device must be made with shielded cables with metallic RFI/EMI connector hoods in
order to maintain compliance with FCC Rules and Regulations.
