EMC (Electromagnetic Compatibility)
In accordance with European Directive 89/336/EEC, the CDM-570/570L 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-570/570L 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
IMPORTANT
In order that the Modem continues to comply with these standards,
observe the following instructions:
• Connections to the transmit and receive IF ports (‘N’ type female connectors)
should be made using a good quality coaxial cable - for example, RG213/U.
• 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.
