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.
Connections to the serial COM port on this device must be made with shielded cables with metallic
RFI/EMI connector hoods in order to maintain compliance with FCC Rules and Regulations.
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.
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.
