Notice
The Industry Canada label identifies certified equipment. This certification means that the equipment meets
certain telecommunications network protective, operational, and safety requirements. The Department
does not guarantee the equipment will operate to the users’ 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 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.
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.
CAUTION:
Users should not attempt to make electrical ground connections by themselves, but should
contact the appropriate inspection authority or an electrician, as appropriate.
