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 telecommunications company. The equip-
ment 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 ex-
tension cord). The customer should be 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 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 con-
nections 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 indication of the maximum number of

requirement that the sum of the Ringer Equivalence Numbers of all the devices 
does not exceed five.

(The term “IC:” before the certification/registration number only signifies that 
the Industry Canada technical specifications were met.)
