Canadian Department of Communications Statement
Notice: The Canadian Department of Communications 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 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 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 such connec-
tions themselves, but should contact the appropriate electric
inspection authority, or electrician, as appropriate.
The Ringer Equivalence Number (REN) assigned to each terminal device denotes
the percentage of the total load to be connected to a telephone loop which is used
by the device to prevent overloading. The termination on a loop may consist of any
combination of devices subject only to the requirement that the total of the Ringer
Equivalent Numbers of all the devices does not exceed 5.0. For Sensaphone 1800,
the AC Ringer Equivalent Number is 0.6B.
