repairs or alterations made by the user of this equipment, or
equipment malfunctions, may give the telecommunication
company cause to request the user to disconnect the
equipment.
WARNING! Users should not attempt to make such connections
themselves, but should contact the appropriate electric
inspection authority, or an electrician, as appropriate.
CAUTION:
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 phone
interface.
The termination on an 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. An alternative indication of the REN is the Load Number
(LN); this number should be divided by 20 to approximate the
equivalent REN. The REN Number of this unit is indicated on
the bottom of your phone.
If your home has specially wired alarm equipment connected
to the phone line, ensure the installation of the A300E does
not disable alarm equipment. If you have questions about what
will disable alarm equipment, consult your phone provider or
a qualified installer.
This Class B digital apparatus complies with Canadian ICES-
