Certification Notice for

Equipment Used in Canada

The Canadian Department of Communications 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 (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—in this case, your 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 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 load numbers of all the devices does

not exceed 100.
