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.
