CANADIAN DEPARTMENT OF COMMUNICATIONS (DOC) REQUIRED
FOR USERS OF DOC-CERTIFIED EQUIPMENT
Read before using this technical manual or installing subject equipment.
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 facili-
ties 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 desig-
nated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment mal-
functions, 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 pre-
caution may be particularly important in rural areas.
Caution:
Users should not attempt to make such connections themselves, but should contact the appro-
priate electric inspection authority, or electrician, as appropriate.
