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
label 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
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.
