Logging and time-stamping (cont.)
That is the only means to leave the function.
If no modifications to values are confirmed, exiting the function corresponds to cancelling the request.
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 displayed for current events. However, log screens include a line indicating the corresponding 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 modified.
