Regulatory Compliance
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.
Warning: Users should not attempt
to make such connections
themselves, but should contact the
appropriate electric inspection
authority, or electrician, or
appropriate.
