How do I set or change the date and time on my VISTA-20P system?

All partitions must be disarmed first, then enter your Master Code followed by [#], [6], and [3] to view the current date and time. Press [*] when the time/date is displayed to enter edit mode, then use [*] to move the cursor forward and [#] to go back as you enter the 2-digit hour, 2-digit minute, AM/PM indicator (1 for PM, 2 for AM), last two digits of the year, 2-digit month, and 2-digit day. Press [*] at the last digit or wait 30 seconds to exit. (Page 25)
