Communications Statements
The following statement applies to this product. The statement for other products intended
for use with this product appears 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.
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.
International Electrotechnical Commission (IEC) Statement
This product has been designed and built to comply with IEC Standard 950.
