Safety Information
This manual should be read in its entirety and all procedures completely understood before
installing or operating the unit, including all notes, cautions and warnings (examples below). The
CAUTION, WARNING, and DANGER statements that appear throughout this manual are
intended to provide critical information for the safety of both the service engineer and operator.
These statements also enhance equipment reliability. The following definitions and symbols for
CAUTION, WARNING, and DANGER as they are used comply with ANSI Z535.2, American
National Standard for Environmental and Facility Safety Signs, and ANSI Z535.4, Product Safety
Signs and Labels, issued by the American National Standards Institute.
Safety Guidelines
• Always use caution and common sense, especially when unsafe conditions or potentially
hazardous voltages are present.
• Repairs must be performed by qualified service personnel only.
• To reduce the risk of electrical shock, do not operate equipment with the cover removed.
• Never install telephone jacks in a wet location unless the jack is designed for that location.
• Never touch uninsulated telephone wires or terminals unless the telephone line is
disconnected at the network interface.
• Never install telephone wiring during an electrical storm.
Antistatic Precautions
This product may containstatic-sensitive devices that are easily damaged by electrostatic discharge
(ESD). ESD occurs when a person whose body has built up static electricity touches a computer
component. ESD can cause computer components to fail. Take proper handling, grounding and
precautionary ESD measures installing parts or cards. Keep parts and cards in antistatic packaging
when not in use or during transport. If possible, use antistatic pads on floor and workbench.
Whenhandlingcomponents,alwaysuseanantistaticwriststrapconnectedto agroundedequipment
frame or chassis. If a wrist strap is not available, periodically touch an unpainted metal surface on
the equipment. Never use a conductive tool, like a screwdriver or a paper clip, to set switches.
Note A note provides special instructions, helpful tips or a general rule. A note is typically a suggestion.
Note IMPORTANT! indicates a note that provides essential operating information you should be particularly
aware of. Important notes are typically strong recommendations.
CAUTION indicates conditions or practices which can cause damage to equipment or loss
of data.
WARNING indicates a potentially hazardous situation which, if not avoided,
may result in minor to moderate injury. It may also be used to alert against unsafe practices.
DANGER indicates an imminently hazardous situation which, if not avoided,
will result in death or serious injury.

Compliance
FCC Part 68 Compliance
This equipment complies with Part 68 of the FCC rules. On the middle backplane connector of the
SpectraComm Dual V.34 is a label that contains, among other information, the FCC registration
number and the Ringer Equivalence Number (REN) for this equipment. If requested, this
information must be provided to the telephone company.
FCC Registration Number: AG6USA-23772-MM-E
Facility Interface Codes: 02LS2
Service Order Code: 9.0Y
Telephone Company Jack Type: RJ45S
All connections to the telephone company must be made using standard plugs and telephone
company-provided jacks or equivalent. A plug and jack used to connect this equipment to the
premises wiring and telephone network must comply with the FCC Part 68 rules and regulations
adoptedby the ACTA. A compliant telephone cord and modular plug is provided with this product.
The plug is designed to be connected to a compatible modular jack that is also compliant. Please
see installation instructions for details.
The REN is used to determine the number of devices that may be connected to a telephone line.
Excessive RENs on a telephone line may result in the SpectraComm Dual V.34 not answering in
response to an incoming call. In most but not all areas, the sum of RENs should not exceed five
(5.0). To be certain of the number of devices that may be connected to a line, as determined by the
total RENs, contact the telephone company.
If the SpectraComm Dual V.34 causes harm to thetelephone network, the telephone company will
notify you in advance that temporary discontinuance of service may be required. If advance notice
is not practical, the telephone company will notify the customer as soon as possible. You will be
advised of your right to file a compliant with the FCC if you believe it is necessary.
The telephone company may from time to time make changes in its facilities, equipment, operations
or procedures that could affect the operation of the SpectraComm Dual V.34. If this happens the
telephone company will provide advance notice in order for you to make necessary modifications
to maintain uninterrupted service.
If trouble is experienced with the SpectraComm Dual V.34, for repair or warranty information,
please contact General DataComm, Inc. at [phone]. If the equipment is causing harm to the
telephone network, the telephone company may request thatyou disconnect the equipment from the
network until the problem is resolved. All repairs or modifications to the equipment must be
performed by General DataComm. Any other repair or modification by a user voids the FCC
Registration and the product warranty.
Connection of this equipment to party lines and coin-operated telephones is prohibited. Connection
to party line service is subject to state tariffs. Contact the state public utility commission, public
service commission or corporate commission for information.
If your premises has specially wired alarm equipment connected to the telephone line, ensure the
installation of the SpectraComm Dual V.34 does not disable your alarm equipment. If you have
questions about this, consult your telephone company or qualified installer.

computer or other electronic device, including FAX Machines, to send any message unless such
message clearly contains the following information:
• Date and time the message was sent.
• Identification of the business or the other entity, or other individual sending the message.
• Telephone number of the sending machine or such business, or other entity, or individual.
This information is to appear in a margin at the top or bottom of each transmitted page or on the
first page of the transmission (Fax Branding). Since any number of fax software packages can be
used with this product, the user must refer to the fax software for setup details.
Part 15 Compliance
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference and
2. This device must accept any interference received, including interference that may cause
undesired operation.
Industry Canada Notification
The Industry Canada label identifies certified equipment. This certification means that the
equipment meets telecommunications network protective, operation and safety requirements as
prescribed in the appropriate Terminal Equipment Technical Requirements document(s). 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. The customer should be aware that compliance with the above
conditions may not prevent degradation of service in some situations.
Repairsto certifiedequipment should be coordinated by a representative designated bythe supplier.
Any repairs or alterations made by the userto 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.
Caution: Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or electrician, as appropriate.
Notice: The Ringer Equivalence Number (REN) assigned to each terminal device provides an
indication of the maximum number of terminals allowed to be connected to a telephone interface.
The termination on an interface may consist of any combination of devices subject only to the
requirement that the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5.
