Canada does not guarantee the equipment will operate to
the 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 (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 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
electric inspection authority or electrician, as appropriate.
Notice: The Ringer Equivalence Number (REN) assigned
to each terminal device provides an indication of the
maximum number of terminals allowed to be connected to a
telephone interface. The termination on an interface may
consist of any combination of devices subject only to the
requirement that the sum of the Ringer Equivalence
Numbers of all the devices does not exceed 5.
