Certification Information
North America Regulatory Statement
This unit was certified by an agency approved in both Canada and the
United States of America. It has been evaluated according to applicable
North American approved standards for product safety for use in Canada
and the United States.
Electronic test and measurement equipment is exempt from FCC part 15,
subpart B compliance in the United States of America and from ICES-003
compliance in Canada. However, EXFO Inc. makes reasonable efforts to
ensure compliance to the applicable standards.
The limits set by these standards are designed to provide reasonable
protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance
with the user guide, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
Modifications not expressly approved by the manufacturer could void the
user's authority to operate the equipment.
European Community Declaration of Conformity
