Memory Preservation

This unit does not require memory preservation batteries. A
built-in memory power back-up system preserves the contents
of the memory during power failures and even when the unit is
unplugged. The unit must be plugged in order to charge the
back-up system.
The memory preservation period after the unit has been
unplugged varies depending on climate and placement of the
unit. On the average, memory contents are protected over a
period of a few weeks after the last time the unit has been
unplugged. This period is shorter when the unit is exposed to a
highly humid climate.
