RECORD SETPOINT CHANGES
(Flash memory card version C.MLM.01.06.xxx and
later or C.MLM.04.02.xxx)
This feature provides a record of the last 75 setpoint
changes. The date and time the setpoint was changed,
the new setpoint value and the Access Level and User
ID used to make the change are stored. The SECURI-
TY LOG Screen and the SECURITY LOG DETAILS
Screen display levels of this information.
On the SECURITY LOG Screen, accessible from the
HISTORY Screen, the setpoint, setpoint category and
new setpoint value are listed and numbered in reverse
order in which they were changed. The most recent is
listed as number 1; the next most recent as number 2,
etc. A PRINT key allows printing this entire list. Since
15 changes can be displayed at one time, multiple
pages could be necessary to display all the changes.
PAGE-UP and PAGE-DOWN keys are provided to
view the entire list. If it is desired to view the details of
a particular setpoint change, select the setpoint change
number with the LOG ENTRY key and then press the
VIEW DETAILS key. This moves to the SECURITY
