A leather wallet holds 12 Deggy Buttons for event registration. Each Button is assigned an event, for example, "door open", "window broken", "missing chair", etc.
The guard carries the event wallet during the tour and touches the corresponding Button of the Event Table with the Pen to any occurrence on the tour. The Pen records the event with the date in its memory.
After the Pen is downloaded, the collected data will appear in the report.
