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 guaran-
tee the equipment will operate to the users satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecom-
munications company. The equipment must also be installed using an acceptable means of connection. 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.

tion authority, or electrician, as appropriate.
