Before installing this equipment, users 
should ensure 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 (tele-
phone extension cord). The customer 
should be aware that compliance with 
the above conditions may not prevent  
degradation of service in some situa-
tions. Repairs to certified equipment 
should be made by an authorized 
Canadian maintenance facility desig- 
nated by the supplier. 

Any repairs or alterations made by the 
user to this equipment, or equipment 
malfunctions, may give the telecommu-
nications 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, tele-
phone lines and internal metallic water 
pipe system, if present, are connected 
together. This precaution may be par-
ticularly 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.

tions were met.)
