The modem uses a system of Fault Prioritization. In each category of fault, only
the highest priority fault is displayed. For instance, if the demodulator is
unlocked, it is irrelevant if there are other receive faults present. If the
IMPORTANT
demodulator then locks, but there is a fault of a lower priority present, this will
then be displayed. This also holds true for the faults reported via the remote
control. This system cuts down drastically on unwanted and irrelevant fault
reporting. A comprehensive list of faults is shown at the end of this section.
