Memory preservation
This unit does not require memory preservation batteries.
A built-in memory power back-up system preserves contents of
the
memory
during
power
failures
and
even
when
the
unit
is
unplugged.
The unit must be plugged in and the power switch turned on and
off once in order to charge the back-up system. Note that since
this
is
not
a
permanent
memory,
the
power
switch
must
be
turned
on
and
off
a
few
times
each
month
the
keep
the
back-up
system
operative.
The
period
of
the
time
during
which
memory
contents
are
preserved
after
power
has
last
been
turned
off
varies
depending
on
climate
and
placement
of
the
unit.
On
the
average,
memory
contents
are
protected
over
a
period
of
3
to
4
weeks
(a
minimum
of
2
weeks)
after
the
last
time
power
has
been
turned
off.
This
period
is
shorted
when
the
unit
is
exposed
to
very
high
humidity
or used
in
an
area
with
an
extremely
humid
climate.
