INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits for

its are designed to provide reasonable protection against harmful inter-
ference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio frequencies. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.
Shielded cables must be used with this unit to ensure compliance with
Class A FCC limits.
Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user’s authority to op-
erate the equipment.

emissions from digital apparatus as set out in the interference-causing
equipment standard entitled “Digital Apparatus,” ICES-003 of the De-
partment of Communications.
Cet appareil nuerique respecte les limites de bruits radioelectriques ap-
plicables aux appareils numeriques de Class A prescrites dans la norme

CANADIAN EQUIPMENT LIMITATIONS
The Industry Canada Certification label identifies certified equipment.
This certification means that the equipment meets certain telecommu-
nications network protective, operational, and safety requirements.
The Department does not guarantee the equipment will operate to the
user's satisfaction.
Before installing this equipment, users should ensure that it is permissi-
ble to be connected to the facilities of the local telecommunications com-
pany. 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 cer-
tified connector assembly (telephone extension cord). 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 Cana-
dian maintenance facility designated by the supplier. Any repairs or al-
terations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to re-
quest 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
waterpipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Users should not attempt to make such connections themselves, but should con-
tact the appropriate electric inspection authority, or an electrician, as appropri-
ate.
The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop which is
used by the device, to prevent overloading. The termination on a loop
may consist of any combination of devices subject only to the equipment
that the total of the LNs of all devices does not exceed 100.
The ringer equivalence number (REN) assigned to each terminal adapter
is used to determine the total number of devices that may be connected
to each circuit. The sum of the RENs from all devices in the circuit
should not exceed a total of 5.0.
