consulting logged (time-
stamped) events
When the PAST EVENTS command is
selected, the system displays a screen
indicating the last event logged. Log
screens are very similar to those dis-
played for current events. However, log
screens include a line indicating the corre-
sponding date and time with the mention
"Appearance of" or "Disappearance of",
followed by the standard text for the event
(see example opposite). Consult the user
manual for indications on the meaning of
events.
The complete log may comprise up to 500
events. If over 500 events have occurred,
only the last 500 may be consulted:
■ press the ▼ key to display the event
that occurred just before the displayed
event. If the displayed event is the oldest
in the list, the display is not modified;
■ press the ▼ key to display the event
that occurred just after the displayed
event. If the displayed event is the most
recent in the list, the display is not modi-
fied.
