Declaration for Canadian users
The Canadian Industry Canada label identifies certified equipment. This certification means that the equipment
meets certain telecommunications network protective, operation, 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 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,
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.
The load number (LN) assigned to each terminal device denotes the percentage of the total load to be
connected to a telephone loop that 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 load numbers of all
the devices does not exceed 100.
