C Radio and TV Interference (FCC Part 15)
This device generates and uses radio frequency energy, and if not installed and used properly-that is, in strict
accordance with the manufacturer?s instructions-may cause interference to radio and television reception. The
device has been tested and found to comply with the limits for a Class A computing device in accordance with
specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection from
such interference in a commercial installation. However, there is no guarantee that interference will not occur in
a particular installation. If the device does cause interference to radio or television reception, which can be deter-
mined by disconnecting the unit, the user is encouraged to try to correct the interference by one or more of the
following measures: moving the computing equipment away from the receiver, re-orienting the receiving
antenna and/or plugging the receiving equipment into a different AC outlet (such that the computing equipment
and receiver are on different branches).
