Install/Replace Clock Battery Backup The TM80 uses 2 "AA" batteries as a backup battery system to provide continuous alarm operation and clock settings in the event of a power failure. If the Backup Batteries have 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 the unit has no display or the Backup Battery Low Icon located on the left of the display isflashing, it is time to replace the backup batteries. 1. Please make sure the AC adaptor is connected. Otherwise all settings may be lost during battery replacement. 2. Open backup battery compartment cover located on the bottom of the unit. 3. Insert two "AA" batteries, checking that the polarity (+ and - ends of the batteries) matches the drawing near the battery compartment. Close the compartment cover.
