Carefully review the information that follows.
Electromagnetic Compatibility (EMC) Compliance
This is a Class B product. In a domestic environment, it may cause radio interference that requires
the user to take adequate protection measures.
EN 55022-1997 Compliance
This equipment meets the radio disturbance characteristic specifications for information technology
equipment as defined in EN 55022-1997.
EN 50082-1:1998 Compliance
This equipment meets the Electromagnetic Compatibility: Generic Immunity standard as defined
in EN50082-1:1998.
In order that the CRS-150 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 (75Ω).
• All 'D' type connectors attached to the unit 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.
Safety Compliance
EN 60950
Applicable testing is routinely performed as a condition of manufacturing on all units to ensure
compliance with safety requirements of safety standard EN 60950 Safety of Information
Technology Equipment including Electrical Business Machines.
This equipment meets the Safety of Information Technology Equipment specification as defined
in EN 60950.
Electrical Safety
The equipment is rated for operation at +12 volts DC and -12 volts DC. It has a maximum power
consumption of 4.5 Watts, and draws a maximum of 250 mA at +12 volts DC and 120 mA at -12
