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:

IMPORTANT
 
 
 
In order that the Modem 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 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.
