How to Set the Clock and Calendar
If your system's clock and cal-
endar is incorrect, it could re-
sult in false alarms. Since many
system functions are time-de-
pendent, it is very important
to regularly check your
system's clock and calendar.
Be sure to reset the clock after
seasonal time changes, such
as Daylight Savings Time. Also,
even if your system has a
backup battery, it is best to
check the clock and calendar
following a power failure.
