IMPORTANT
To ensure that the Modem continues to comply with these standards,
observe the following instructions:
• Connections to the transmit and receive IF ports (Type ‘BNC’ female connectors for the
CDM-Qx, Type ‘N’ female connectors for the CDM-QxL) should be made using a good
quality coaxial cable; e.g., RG58/U (50
Ω) 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.
