Communications Statements
The following statement applies to this product. The statement for other products intended
for use with this product will appear in their accompanying manuals.
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.
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.
