1.3  INDUSTRY CANADA NOTICE 

The Canadian Department of Communications label identifies cer-

tified 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 individ-
ual service may be extended by means of a certified connector assem-
bly (telephone extension cord).  The customer should be aware that
compliance with the above condition may not prevent degradation of
service in some situations. Repairs to some certified equipment should
be made by an authorized maintenance facility designated by the sup-
plier. 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 ground connections of the
power utility, telephone lines and  internal metallic  water pipe system,
are connected together.  This protection may be particularly important
in rural areas.
