Guide

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—in this case, your 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.
