This unit uses a backup battery system to provide continuous alarm
operation and clock settings in the event of a power failure. If the
Backup Battery has been installed and a power failure occurs or the
AC cord is accidentally disconnected, the display will not remain lit,
but the current time and alarm time setting will be temporarily
maintained. Otherwise, you must reset the time and alarm setting.
