CE NOTICE

We certify that the apparatus identiﬁed in this document conforms to the require-

ments of Council Directive 1999/5/EC on the approximation of the laws of the

member states relating to Radio and Telecommunication Terminal Equipment

and the mutual recognition of their conformity.

RADIO AND TV INTERFERENCE

This equipment generates and uses radio frequency energy, and if not installed

and used properly—that is, in strict accordance with the manufacturer's instruc-

tions—may cause interference to radio and television reception. This equipment

has been tested and found to comply with the limits for a Class A computing

device in accordance with the speciﬁcations in Subpart B of Part 15 of FCC rules,

which are designed to provide reasonable protection from such interference in a

commercial installation. However, there is no guarantee that interference will not

occur in a particular installation. If the equipment causes interference to radio or

television reception, which can be determined by disconnecting the cables, try to

correct the interference by one or more of the following measures: moving the

computing equipment away from the receiver, re-orienting the receiving antenna,

and/or plugging the receiving equipment into a different AC outlet (such that the

computing equipment and receiver are on different branches).

FCC PART 68

This equipment complies with Part 68 of FCC rules and the requirements adopted

by ACTA. On the bottom side of this equipment is a label that contains—among

other information—a product identiﬁer in the format US: AAAEQ##TXXXX. If

requested, this number must be provided to the telephone company.

The method used to connect this equipment to the premises wiring and telephone

network must comply with the applicable FCC Part 68 rules and requirements

adopted by the ACTA.

If this equipment causes harm to the telephone network, the telephone company

will notify you in advance that temporary discontinuance of service may be

required. But if advance notice isn’t practical, the telephone company will notify

the customer as soon as possible. Also, you will be advised of your right to ﬁle a

complaint with the FCC if you believe it is necessary.

The telephone company may make changes in its facilities, equipment, opera-

tions or procedures that could affect the operation of the equipment. If this hap-

pens the telephone company will provide advance notice in order for you to make

necessary modiﬁcations to maintain uninterrupted service.

T1/E1 LINK EXTENDERS

If trouble is experienced with this equipment, for repair or warranty information,

please contact our company. If the equipment is causing harm to the telephone

network, the telephone company may request that you disconnect the equipment

until the problem is resolved.

Connection to party line service is subject to state tariffs. Contact the state public

utility commission, public service commission or corporation commission for

information.

INDUSTRY CANADA NOTICE

This equipment meets the applicable Industry Canada Terminal Equipment Tech-

nical Speciﬁcations. This is conﬁrmed by the registration number. The abbrevia-

tion, IC, before the registration number signiﬁes that registration was performed

based on a Declaration of Conformity indicating that Industry Canada technical

speciﬁcations were met. It does not imply that Industry Canada approved the

equipment.

This Declaration of Conformity means that the equipment meets certain telecom-

munications network protective, operational and safety requirements. The

Department does not guarantee the equipment will operate to the user's satisfac-

tion. Before installing this equipment, users should ensure that it is permissible to

extension cord). The customer should be aware that compliance with the above

condition may not prevent degradation of service in some situations. Repairs to

some certiﬁed equipment should be made by an authorized maintenance facility

designated by the supplier. Any repairs or alterations made by the user to this

equipment, or equipment malfunctions, may give the telecommunications com-

pany cause to request the user to disconnect the equipment. Users should ensure

for their own protection that the ground connections of the power utility, tele-

phone lines and internal metallic water pipe system, are connected together. This

protection may be particularly important in rural areas.
