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 by extended by
means of a certified connector assembly (telephone extension cord). 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.
Users should ensure, for their own protection, 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.
