CANADIAN EQUIPMENT LIMITATIONS

Notice: The Canadian Industry and Science Canada label identi- fies certified equipment. This certification means that the equip- ment 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 per- missible to be connected to the facilities of the local telecommuni- cations 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 (tele- phone extension cord). The customer should be aware that com- pliance 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 com- pany 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 in- ternal metallic water pipe system, if present, are connected to- gether. This precaution may be particularly important in rural areas.

Users should not attempt to make such connections them- selves, but should contact the appropriate electric inspection authority, or an 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 which is used by the device, to prevent overloading. The ter- mination on a loop may consist of any combination of devices subject only to the requirement that the total of the Load Numbers of all devices does not exceed 100.
