Before installing this equipment, users should make sure 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 make sure, 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.
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.
