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 the 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, tele-
phone 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.
The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maxi-
mum 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 Equiva-
lence Numbers of all the devices does not exceed 5.
