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.
