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 energy. If this equipment is not installed and used in accordance with the
manufacturer’s instructions, it may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment

This board is designed for installation in a shielded enclosure (metal or plastic with conductive
coating). Shielded cables may be required on LAN and serial ports to assure compliance with FCC
regulations.
A copy of the test report will be provided on request.
Note: apu has been tested as a CPU board, installed in an enclosure, with the top cover removed.
No further testing should be required if the board is used with other FCC tested modular
components. Please see http://www.fcc.gov/oet/ for more details. The responsible party for FCC is
the importer.
