Deletion of an event consists of removing audio and text data. Event header text files are always kept even when
event data is deleted. So deletion does not purge the DASDEC II of its record of a past EAS event.
Use the button to save changes to this page.
At the bottom of the page is printed a chart of the current storage space use. The chart shows the total capacity in
Megabytes, the used space and available space in Megabytes, and the space used for specific alert event types.
Minimum space is maintained between 150 MB and 100 MB. If the DASDEC II available storage space ever drops
below 100 Megabytes, the oldest events will be chosen for automatic deletion. This pruning process is initiated after
every alert event and at midnight every night. If a minimum space condition is detected, event data is deleted until at
least 150 MB of space becomes available. The deletion time periods are also automatically adjusted downward if
needed to reflect the dates of the deleted events.
