REN

s on a telephone line may result in the devices not ringing in response to an incoming call. In most areas, the sum of REN

s should not exceed 

five (5.0). To be certain of the number of devices that may be connected to a line, as determined by the total REN

s, contact the local telephone 

company.

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.
