The event log can store up to 98 events. When a fault condition occurs, it is time-stamped
and put into the log. Next to the FT (for fault) indicator is either the TM number, RM
(redundant mod/demod fault) or SW (switch fault). Similarly, when the fault condition
clears, this is also recorded, as shown below:

To clear the Event Log, select CLEAR-ALL. The previous menu returns.
However, if there are faults present on the unit at this time, they will be re-time-stamped,
and new log entries will be generated.
