This device may not cause harmful interference.
This device must accept any interference received, including interference that may cause undesired operations.
This equipment has been tested and found to comply with the limits for a Class B digital device pursuant to Part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
If this equipment does cause harmful interference to radio/television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.

iv Information for Canadian Users
Information for Canadian Users
The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain
telecommunications network protective, operation and safety requirements. The Industry Canada does not guarantee
that the equipment will operate to a user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be installed using an acceptable method of connection. In some
cases, the company's inside wiring associated with a single line individual service may be extended by means of a
certified connector assembly. The customer should be aware that the compliance with the above conditions may not
prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the
supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the equipment.
For their own protection, users should ensure that the electrical ground connections of the power utility, telephone lines
and internal metallic water pipe system, if present, are connected together. This precaution may be particularly
important in rural areas.
CAUTION
Users should not attempt to make such connections themselves, but should contact the appropriate electrical inspection
authority, or electrician, as appropriate.
NOTE
This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the
radio interference regulations of Industry Canada.
