Canadian Department of Communications Notices
Class A Limits
The digital apparatus does not exceed the Class A limits for radio noise emissions from
digital apparatus as set out in the Radio Interference Regulations of the Canadian
Department of Communications.
Load Number
The Load Number (LN) assigned to each terminal device denotes the percentage of the
total load to be connected to a telephone loop used by the device to prevent overloading.
The termination of a loop may consist of any combination of devices subject only to the
requirement that the sum of the load numbers of all devices does not exceed 100.
Attachment Limitation
The Canadian Department of Communications label identifies certified equipment.
This certification means that the equipment 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 telecommunications company. An acceptable method of
connection must be used to install the equipment. 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 that the user disconnect the equipment.
For their own protection, users should ensure 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 electric inspection authority or
electrician as appropriate.
