FCC/IC RFI STATEMENTS

FEDERAL COMMUNICATIONS COMMISSION AND INDUSTRY CANADA

RADIO-FREQUENCY INTERFERENCE STATEMENTS

Class B Digital Device. This equipment has been tested and found to comply
with the limits for a Class B computing device pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. However, there is no
guarantee that interference will not occur in a particular installation. This
equipment generates, uses, and can radiate radio frequency energy, and, if
not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. If this equipment does
cause harmful interference to radio or telephone reception, which can be
determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.

• Consult an experienced radio/TV technician for help.

Caution:

Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s
authority to operate the equipment.

To meet FCC requirements, shielded cables and power cords are required to
connect this device to a personal computer or other Class B certified device.

This digital apparatus does not exceed the Class B limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of Industry Canada.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les
limites applicables aux appareils numériques de classe B prescrites dans le Règlement
sur le brouillage radioélectrique publié par Industrie Canada.

FCC PART 68 MODEM STATEMENT

FEDERAL COMMUNICATIONS COMMISSION MODEM STATEMENT

1. The Federal Communications Commission (FCC) has established rules
which permit this device to be directly connected to the telephone
network with standardized jacks. This equipment should not be used on
party lines or coin lines.

2. If this device is malfunctioning, it may also be causing harm to the tele­phone network; this device should be disconnected until the source of the
problem can be determined and until the repair has been made. If this
is not done, the telephone company may temporarily disconnect service.

3. If you have problems with your telephone equipment after installing
this device, disconnect this device from the line to see if it is causing the
problem If it is, contact your supplier or an authorized agent.

4. The telephone company may make changes in its technical operations
and procedures. If any such changes affect the compatibility or use of
this device, the telephone company is required to give adequate notice
of the changes.

5. If the telephone company requests information on what equipment is
connected to their lines, inform them of:

a. The telephone number that this unit is connected to.

b. The ringer equivalence number.

c. The USOC jack required: RJ-11C.

d. The FCC registration number.

Items (b) and (d) can be found on the unit’s FCC label. The ringer
equivalence number (REN) is used to determine how many devices can
be connected to your telephone line. In most areas, the sum of the
RENs of all devices on any one line should not exceed five (5.0). If too
many devices are attached, they may not ring properly.

6. In the event of an equipment malfunction, all repairs should be
performed by your supplier or an authorized agent. It is the
responsibility of users requiring service to report the need for service to
the supplier or to an authorized agent.

INDUSTRY CANADA MODEM STATEMENT

The Industry Canada (IC) label identifies certified equipment. This
certification means that the equipment meets certain telecommunications­network protective, operation, and safety requirements. Industry Canada
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 (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—in this case, Black Box. 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.

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 (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 the devices does not exceed 100.
