Federal Communications Commission

Radio Frequency Interference Statement

This equipment has been tested and found to comply with the limits for a Class A dig-

ital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference when the equipment is operated in

a commercial environment. This equipment generates, uses, and can radiate radio fre-

quency energy and, if not installed and used in accordance with the instruction man-

ual, 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.

Canadian Emissions Requirements

This digital apparatus does not exceed the Class A limits for radio noise emissions

from digital apparatus as set out in the interference-causing equipment standard enti-

tled “Digital Apparatus,” ICES-003 of the Department of Communications.

Cet appareil nuerique respecte les limites de bruits radioelectriques applicables aux

appareils numeriques de Class A prescrites dans la norme sur le materiel brouilleur:

“Appareils Numeriques,” NMB-003 edictee par le ministre des Communications.

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

operate the equipment.

Canadian Equipment Limitations

Notice: The Canadian Industry and Science Canada label identifies certified equip-

ment. 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 con-

nected to the facilities of the local telecommunications company. The equipment must

also be installed using an acceptable methods of connection. In some cases, the com-

pany’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 limitations may not prevent degra-

dation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian mainte-

nance 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 pre-

vent 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.

Users should not attempt to make such connections themselves, but

should contract the appropriate electric inspection authority, or an elec-

trician, as appropriate.
