Communications Statements
The following statement applies to this product. The statement for other products
intended for use with this product appears in their accompanying documentation.
Federal Communications Commission (FCC) Statement
Note: 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 limits are
designed to provide reasonable protection against harmful interference 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
communications. 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.
Properly shielded and grounded cables and connectors must be used in order to
meet FCC emission limits. Neither the provider nor the manufacturer are responsible
for any radio or television interference caused by using other than recommended
cables and connectors or by unauthorized changes or modifications to this
equipment. Unauthorized changes or modifications could void the user's authority to
operate the equipment.
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.
European Union (EU) Statement
This product is in conformity with the protection requirements of EU Council Directive
89/336/EEC on the approximation of the laws of the Member States relating to
electromagnetic compatibility. The manufacturer cannot accept responsibility for any
failure to satisfy the protection requirements resulting from a non-recommended
modification of the product, including the fitting of option cards supplied by third
parties. Consult with your dealer or sales representative for details on your specific
hardware.
This product has been tested and found to comply with the limits for Class A
Information Technology Equipment according to CISPR 22 / European Standard EN
55022. The limits for Class A equipment were derived for commercial and industrial

environments to provide reasonable protection against interference with licensed
communication equipment.
Attention: This is a Class A product. In a domestic environment this product may
cause radio interference in which case the user may be required to take adequate
measures.
International Electrotechnical Commission (IEC) Statement
This product has been designed and built to comply with IEC Standard 950.
United Kingdom Telecommunications Safety Requirements
This equipment is manufactured to the International Safety Standard EN60950 and
as such is approved in the UK under the General Approval Number
NS/G/1234/J/100003 for indirect connection to the public telecommunication network.
The network adapter interfaces housed within this equipment are approved
separately, each one having its own independent approval number. These interface
adapters, supplied by the manufacturer, do not use or contain excessive voltages.
An excessive voltage is one which exceeds 70.7 V peak ac or 120 V dc. They
interface with this equipment using Safe Extra Low Voltages only. In order to
maintain the separate (independent) approval of the manufacturer's adapters, it is
essential that other optional cards, not supplied by the manufacturer, do not use
main voltages or any other excessive voltages. Seek advice from a competent
engineer before installing other adapters not supplied by the manufacturer.
Avis de conformité aux normes du ministère des Communications du
Canada
Cet appareil numérique de la classe A respecte toutes les exigences du Réglement
sur le matériel brouilleur du Canada.
Canadian Department of Communications Compliance Statement
