The iHM46 uses a CR2032 button cell battery (included with instructions) to keep alarm and clock settings in the event of a power failure and 4 “AA” batteries, not included, for portable operation. If the Backup Battery has been installed and a power failure occurs or the AC adaptor is accidentally disconnected, the display backlight will not remain lit, but the current time and alarm time settings will be temporarily maintained. Otherwise, you must reset the time and alarm settings. If 4 “AA” batteries are installed, the alarm will operate when the unit is not connected to the AC adaptor.

  2. Open and remove the battery compartment door located at the bottom of the unit.
