Operation in vehicles or other transportable installations which are equipped to provide a
stable environment is permitted. If such vehicles do not provide a stable environment,
safety of the equipment to EN60950 may not be guaranteed

Telecommunications Terminal Equipment Directive

In accordance with the Telecommunications Terminal Equipment Directive 91/263/EEC,
this equipment should not be directly connected to the Public Telecommunications
Network.







EMC (Electromagnetic Compatibility)

The CRS-100 1:1 Redundancy Switch has been demonstrated, by independent testing, to
comply with the following standards:

Emissions:

EN 55022 Class B - Limits and methods of measurement of radio
interference characteristics of Information Technology Equipment.


FCC Part 15 Class B

Immunity:

EN 50082 Part 1 - Generic immunity standard, Part 1: Domestic,
commercial and light industrial environment.


In order that the CRS-100 continues to comply with these standards, observe the
following instructions:

• Connections to the transmit and receive IF ports (BNC female connectors) should

be made using a good quality coaxial cable - for example RG58/U (50

Ω) or

RG59/U (75

Ω).

• All 'D' type connectors attached to the unit must have back-shells which provide

continuous metallic shielding. Cable with a continuous outer shield (either foil or
braid, or both) must be used, and the shield must be bonded to the back-shell.

• The equipment must be operated with its cover on at all times. If it becomes

necessary to remove the cover, the User should ensure that the cover is correctly
re-fitted before normal operation commences.
