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.
If batteries are inserted within two minutes, the
M28413
time and day will not have to be reset. All other
settings are permanently stored in memory and
do not require battery power.
