How do I set or change the date and time on the system?

Enter your security code, press [#], then press [6] [3] to display the current time and date. When the time/date is displayed, press [*] to enter edit mode — a cursor will appear under the first digit of the hour. Enter the 2-digit hour, 2-digit minutes, press [1] for PM or [2] for AM, then enter the last two digits of the year, 2-digit month, and 2-digit day. Press [*] when the cursor is at the last digit to exit, or wait 10 seconds. (Page 21)
