Getting Started Guide

Compliance Information
Radio
and TV
Interference
The WAN Access Router 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 WAN Access Router have been tested and found to comply with the limits for a Class A com-
puting 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 guar-
antee that interference will not occur in a particular installation. If The WAN Access Router does cause inter-
ference to radio or television reception, which can be determined 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).
CE Notice
The CE symbol on your Black Box equipment indicates that it is in compliance with the Electromagnetic
Compatibility (EMC) directive and the Low Voltage Directive (LVD) of the European Union (EU). A Certifi-
cate of Compliance is available by contacting Technical Support.
