The iZBT20 ships with a CR2450 battery installed for backup to provide
continuous alarm operation and clock settings in the event of a power failure.
Remove the pull tab from the battery compartment on the bottom of the unit
before use
. If a power failure occurs or the AC cord 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.
Note
: When the backup battery is low and needs to be replaced, ”Low Battery”
will flash on the display when the unit is powered on. To replace, follow
steps below:
1. Please make sure the AC adapter is
connected. Otherwise all settings may be
lost during battery replacement.
2. Use a Phillips screwdriver to open the
backup battery compartment door located
on the bottom of the unit.
3. Remove the exhausted battery. Insert a new
CR2450 battery by easing it under the tabs
in the battery well and pressing down. Make
sure the side is facing up.
4. Close the battery compartment door and
tighten the battery door screw.
Note: Make sure you dispose of battery
properly (see your local regulations).
