Radio and TV interference regulations for the United States
and Canada
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.
This device also complies with Part 15 of the U.S. Federal Communications Commission (FCC) rules. Operation is
subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired operation.
Your Microsoft hardware device(s) can radiate radio frequency (RF) energy. If not installed and used in strict
accordance with the instructions given in this printed documentation, the device may cause harmful interference
with other radio-communications devices (for example AM/FM radios, televisions, baby monitors, cordless
phones, etc.). Any cable that is connected to the device must be a shielded cable that is properly grounded. There
is, however, no guarantee that RF interference will not occur in a particular installation.
Your Microsoft hardware device has been tested, and it complies with the limits for a Class B digital device in
accordance with the specifications in Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful RF interference in a residential installation.
To determine if your hardware device is causing interference to other radio-communications devices, disconnect
the device from your computer. If the interference stops, it was probably caused by the device. If the interference
continues after you disconnect the hardware device, turn the computer off and then on again. If the interference
stopped when the computer was off, check to see if one of the input/output (I/O) devices or one of the
computer's internal accessory boards is causing the problem. Disconnect the I/O devices one at a time and see if
the interference stops.
If this hardware device does cause interference, try the following measures to correct it:
• Relocate the antenna of the other radio-communications device (for example AM/FM Radios, televisions, baby
monitors, cordless phones, etc) until the interference stops.
• Move the hardware device farther away from the radio or TV, or move it to one side or the other of the radio or
TV.
• Plug the computer into a different power outlet so that the hardware device and radio or TV are on different
circuits controlled by different circuit breakers or fuses. If necessary, ask your computer dealer or an
experienced radio-TV technician for more suggestions. For more information about interference issues, go to
the FCC Web site at:

You can also call the FCC at 1-888-CALL FCC to request Interference and Telephone Interference fact sheets.
