DOC Certification Label
The Canadian Department of Communications (DOC) 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:
Do not attempt to make electrical ground
connections yourself; contact the
appropriate electric inspection authority
or an electrician.
