NOTICEThe Industry Canada label identifies certified equipment. This certifica-
tion means that the equipment meets certain telecommunications
networks protective, operational and safety requirements. The Depart-
ment does not guarantee the equipment will operate to the user’s
satisfaction.
Before installing this equipment, users should ensure that it is permitted
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 conditions may not prevent
deterioration of service in some situations.
The Ringer Equivalence Number (REN) assigned to each terminal device
provides an indication of the maximum number of terminal allowed to
be connected to a telephone interface. The termination on an interface
may consist of any combination of devices subject only to the require-
ment that the sum of the Ringer Equivalence Number of all the devices
does not exceed 5.
The REN of this equipment is 0.3.
Even if the dual-line option is installed, the REN is applicable to each
port.
Repairs to certified equipment should be made by an authorized Cana-
dian 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 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.
