Overview Board Layout
“NOTICE: The Canadian Department of Communications label identifies certified equipment. This certification means that the equip-
ment meets certain telecommunications 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 permissible to be connected to the facilities of the local telecommunica-
tions company. 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 certified connector assembly (telephone extension
cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situa-
tions.
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.
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 requirement that the total of the Load Numbers of all the devices does not exceed 100.”
Industry Canada (IC) Compliance - “This digital apparatus does not exceed the Class A limits for radio noise emissions from digital
apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.”
IC Registration Number: 2132A-UDACT2 REN (Ringer Equivalence Number): 0.0B
