NFORMATION
NOTICE: The Industry Canada label identifies certified equipment. This certification means that the equipment
meets certain telecommunications network protective, operational and safety requirements. Industry Canada does
not guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should be sure 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 condition may not prevent degradation of service in some situations.
Repairs to some certified equipment should be made by an authorized 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 be sure 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.
NOTICE
The ringer equivalence number (REN) assigned to each terminal device provides
an indication of the maximum number of terminals allowed to be connected to the
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 5.
