Regulatory Information
United States Radio and TV Interference Regulations
This device 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.
The Microsoft hardware device(s) that accompanies this software can radiate radio frequency (RF) energy. If not
installed and used in strict accordance with the instructions given in this User’s Guide, 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:
O Relocate the antenna of the other radio-communications device (for example AM/FM Radios, televisions,
baby monitors, cordless phones, etc.) until the interference stops.
O 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.
O 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.
O If necessary, ask your computer dealer or an experienced radio-TV technician for more suggestions. You may
find helpful information about interference issues at the following FCC Web site:
http://www.fcc.gov/cgb/consumerfacts/interference.html, or call the FCC at 1-888-CALL FCC to request from
the operator “Interference and Telephone Interference” fax sheets.
