Preface	MN/CDM600.IOM

EMC (Electromagnetic Compatibility)

In accordance with European Directive 89/336/EEC, the CDM-600 Modem 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 50082 Part 1 - Generic immunity standard, Part 1: Domestic,
	commercial and light industrial environment.

Additionally, the CDM-600 has been shown to comply with the following standards:

EN 61000-3-2	Harmonic Currents Emission
EN 61000-3-3	Voltage Fluctuations and Flicker
EN 61000-4-2	ESD Immunity
EN 61000-4-4	EFT Burst Immunity
EN 61000-4-5	Surge Immunity
EN 61000-4-6	RF Conducted Immunity
EN 61000-4-8	Power frequency Magnetic Field Immunity
EN 61000-4-9	Pulse Magnetic Field Immunity
EN 61000-4-11	Voltage Dips, Interruptions, and Variations Immunity
EN 61000-4-13	Immunity to Harmonics

In order that the Modem continues to comply with these standards, observe the following instructions:

IMPORTANT

•Connections to the transmit and receive IF ports (BNC female connectors) should be made using a good quality coaxial cable - for example RG58/U (50Ω or RG59/U (75Ω).

•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 re-fitted before normal operation commences.
