Canada

Notice To The Users Of The Canadian

Public Switched Telephone Network

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. 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 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 the user to disconnect the

equipment.

Users should ensure for their own protection that the electrical

ground connections of the power utility, telephone line 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.

The Load Number for this equipment is listed on the modem’s

label. 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 devices does not exceed 100.
