Industry Canada Technical Specifications
This product meets the applicable Industry
Canada technical specifications.
Before installing this equipment, users should
ensure that it is permissible to be connected
to the facilities of the local telecommunica-
tions 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 degrada-
tion 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 malfunc-
tions, may give the telecommunications com-
pany 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 electrical inspection
authority, or electrician, as appropriate.
The Ringer Equivalence Number is an indi-
cation of the maximum number of terminals
allowed to be connected to a telephone
interface. The termination on an interface
may consist of any combination of devices
subject only to the requirement that the sum
of the Ringer Equivalence Numbers of all the
devices does not exceed five.
(The term “IC:” before the certification/regis-
tration number only signifies that the Industry
Canada technical specifications were met.)
