Installing Backup Battery
The iHM45 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 to maintain alarm 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
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,
alarm will operate when unit is not connected to AC adaptor.
1. Please make sure the AC adaptor is connected. Otherwise all settings may
be lost during battery replacement.
2. Open and remove the battery compartment door located on the bottom of
the unit.
3. Pinch the backup battery release tab and pull the backup battery holder free.
4. Insert one CR2032 button cell battery with the + side facing upwards.
5. Replace the backup battery holder into the unit, then replace the battery
compartment door.
Notes:
• Make sure you dispose of battery properly (see your local regulations).
• Buttons will not function if only back up battery installed.
• Replace the CR2032 battery when you see the Low Battery indicator flashing in the display.
