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, tele-
phone lines, and internal metallic water pipe system, if
present, are connected together. This precaution may be
particularly important in rural areas.
Users should not attempt to make such
connections themselves, but should contact
the appropriate electric inspection author-
ity, or an electrician, as appropriate.
