FEDERAL COMMUNICATIONS COMMISSION RADIO FREQUENCY

INTERFERENCE STATEMENT

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

a Class A digital device, pursuant to Part 15 of the FCC Rules. These lim-

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.

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 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

sur le materiel brouilleur: “Appareils Numeriques,” NMB-003 edictee

par le ministre des Communications.

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.

Notes provide additional useful information.

Cautions signify information that could prevent service inter-

ruption.

Warnings provide information that could prevent damage to the

equipment or endangerment to human life.
