Electromagnetic Compatibility
This Satellite Modem conforms to the provisions of EMC Directive 2004/108/EC and
complies with the following standards:
1. Emissions: EN 55022:2006 Class B – ‘Information Technology Equipment –
Radio Disturbance Characteristics – Limits and Methods of Measurement’.
2. Immunity:
EN 50024:1998+A1:2001+A2:2003 – ‘Information Technology
Equipment – Immunity Characteristics – Limits and Methods of Measurement ’.
Extensive testing has been performed to ensure that the unit meets these specifications
when configured with any or all of its available hardware options.
To ensure that the modem maintains compliance with
electromagnetic compatibility standards please observe the
following points:
The equipment must be operated with its cover on at all times. If it is necessary to remove
the cover for any reason, then you must ensure that the cover is correctly refitted before
normal operation.
For the baseband data interfaces, all ‘D’ type connectors must have grounding fingers on
the plug shell to guarantee continuous shielding. The back-shells must comply with the
requirements of VDE 0871 and FCC 20708, providing at least 40dB of attenuation from
30 MHz to 1 GHz. A good quality cable with a continuous outer shield, correctly
grounded, must be used.
Connections to transmit and receive IF interfaces must be made with double-screened
coaxial cable (for example, RG223/U).
