1.5 Canadian Limitations Notice
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 a telephone interface. The
termination of a 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.
Notice: The Industry Canada label identifies certificated equipment. This
certification means that the equipment meets certain telecommunica-
tions network protective, operational and safety requirements. The
Industry Canada does not guarantee the equipment will operate to the
user’s satisfaction.
Before installing this equipment, users should ensure that it is permis-
sible to be connected to the facilities of the local telecommunications
company. The equipment must also be installed using an acceptable
method of connection. 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
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 them-
selves, but should contact the appropriate electric inspection authority,
or electrician, as appropriate.
