FCC Information - Class B

The sound card has been tested, and it complies with the limits for a Class B computing device in accordance with
the specifications in Part 15 of the Federal Communications Commission (FCC) rules.  These limits are designed to
provide reasonable protection against harmful RF interference in a residential installation.  There is, however, no
guarantee that RF interference will not occur in a particular installation.

To determine if your hardware device is causing interference, disconnect the device from your computer.  If the
interference stops, it probably was caused by the device.  If the interference continues, disconnect the hardware
device, then 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 of 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 your computer does cause interference, try the following measures to correct it:

Relocate the radio or TV antenna until the interference stops.

Move the computer 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 computer 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.  You may find
helpful information in the booklet How to Identify and Resolve Radio-TV Interference Problems (stock number
004-000-00345-4), published by the FCC, which is available from the U.S. Government Printing Office,
Washington, D.C. 20402.
