4-2 History Log Key:
The
History Log
is used to record certain events that reflect the status and operating
mode of the unit.
There are 64 lines (00 through 63).
It is read by holding down the
Alarm Scan
button. Each time the button is pressed, the
log is read sequentially with the most recent event being displayed first. After 00 is
displayed, the system will cycle around to 63.
After 64 events are logged, the system will start recording again at 00.
