Install fresh batteries immediately when the
REPLACE BATTERY warning begins flashing. The
warning flashes about two months before the
batteries are depleted.
Even if the warning does not appear, you
should replace batteries once a year, or before
leaving home for more than a month.
Batteries provide backup power to the display
during power interruptions. All settings are per-
manently stored in memory, and do not require
battery power.
