FEDERAL COMMUNICATIONS COMMISSION (FCC), INDUSTRY CANADA (IC), AND
VOLUNTARY CONTROL COUNCIL FOR INTERFERENCE (VCCI) RADIO-FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly, that is, in
strict accordance with the manufacturer’s instructions, may cause interference to radio communication. It has been tested
and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart J of
Part 15 of FCC rules, which are designed to provide reasonable protection against such interference when the equipment
is operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference,
in which case the user at his own expense will be required to take whatever measures may be necessary to correct the
interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority
to operate the equipment.
This digital apparatus does not exceed the Class A 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 la classe
A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.
EUROPEAN UNION DECLARATION OF CONFORMITY
This equipment has been tested and found to comply with the limits for a class A computing device in accordance with the
specifications in the European standard EN 55022. These limits are designed to provide reasonable protection against
harmful interference. This equipment generates, uses and can radiate radio-frequency energy, and if not installed and
used in accordance with the instructions, might cause harmful interference to radio or television reception. However,
there is no guarantee that harmful interference will not occur in a particular installation. If this equipment does cause
interference to radio or television reception, which can be determined by turning the equipment on and off, you can
correct the interference with one or more of the following measures:
(a) Reorient or relocate the receiving antenna.
(b) Increase the separation between the equipment and the receiver.
(c) Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
(d) Consult the supplier or an experienced radio/TV technician for help.
This equipment has also been tested and found to comply with European standard EN 50082-1:1992.

FCC PHONE-EQUIPMENT STATEMENT

FCC REQUIREMENTS FOR TELEPHONE-LINE EQUIPMENT
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 Black Box.
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.
You’ll also be advised of your right to file an FCC complaint.
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). 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 Black Box. It is your responsibility
to tell us that your equipment needs to be serviced.

CERTIFICATION NOTICE FOR TELEPHONE-LINE EQUIPMENT USED IN CANADA
The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain
telecommunications-network protective, operational, and safety requirements. Industry Canada does not guarantee the
equipment will operate to your satisfaction.
Before installing this equipment, you 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). 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 maintenance facility—in this case, Black Box. Any
equipment malfunctions, or any repairs or alterations you make to this equipment, may give the telecommunications
company cause to ask you to disconnect the equipment.
You should ensure for your own protection that the electrical ground connections of the power utility, telephone lines,
and internal metallic water-pipe system, if present at your site, 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 what percentage of the total load to be connected
to a telephone loop is caused by the device. In order to prevent overloading, the termination on a loop may consist
of any combination of devices, subject only to the requirement that the sum of the load numbers of all the devices
does not exceed 100.
