CDM-840 Remote Router Revision 0
Preface MN-CDM840
xii
Operation in vehicles or other transportable installations that 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.
CE Mark
Comtech EF Data declares that the CDM-840 meets the necessary requirements for the CE Mark.
RoHS Compliance
This unit satisfies (with exemptions) the requirements specified in the European Union Directive on
the Restriction of Hazardous Substances, Directive 2002/95/EC, (EU RoHS).
EMC (Electromagnetic Compatibility) Compliance
In accordance with European Directive 2004/108/EEC, the CDM-840 has been shown, 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.
(Also tested to FCC Part 15 Class B.)
Immunity: EN 55024 – Information Technology Equipment: Immunity
Characteristics, Limits, and Methods of Measurement.
Additionally, the CDM-840 has been shown to comply with the following standards:
EN 61000-3-2 – Harmonic Currents Emission;
EN 61000-3-3 – Voltage Fluctuations and Flicker.
IMPORTANT
To ensure that the CDM-840 continues to comply with these standards,
observe the following instructions:
• Connections to the transmit and receive L-Band ports (Type ‘N’ female connectors)
should be made using a good quality coaxial cable.
• All 'D' type connectors attached to the rear panel must have back-shells that 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 refitted before normal
operation commences.
