Canadian Department of Communications certification label
NOTICE:
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 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 (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 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.
Caution:
Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or electrician, as
appropriate.
