Regulatory Compliance
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 themselves, but should
contact the appropriate electrical inspection
authority, or electrician, as appropriate.
The Ringer Equivalence Number is an indi-

subject only to the requirement that the sum
of the Ringer Equivalence Numbers of all
the devices does not exceed five.
(The term “IC:” before the certification/reg-
istration number only signifies that the
Industry Canada technical specifications
were met.)
