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.
WARNING: Users should not attempt to make such connection 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 numbers 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.
