and/or deformation.
lemory
backup
IThe
unit
contains
a
battery
which
maintains the contents
of
memory
while the
main
power
is off.
The
expected
life
of
this
battery
is
5 years
or
more.
However,
to
avoid the
unexpected
loss
of
memory
data,
it
is
strongly
recommended
that
you change
the battery
every 5
years.
Please
be aware
that
the actual
life
of
the battery
will
depend
on
the
physical
environment
(especially
temperature)
in
which
the
unit
is
used.
When
it
is
time
to
change
the
battery,
consult
with
qualified
service
personnel.
IWhen
the
battery
becomes weak
the following
message
will
appear
in
the
display: "Internal
battery
low".
Please
change
the battery
as
soon as
possible
to
avoid the
loss
of
memory
data.
#Please
be
aware
that
the
contents
of
memory may
at
times
be
lost;
when
the
unit
is
sent
for
repairs or
when
by
some
chance
a malfunction
has
occurred.
Important data
should
be
stored
on
a
DATA
(Memory)
card, or written
down
on
paper. During
repairs,
due
care
is
taken
to
avoid
the loss
of
data.
However,
in
certain
cases, (such as
when
circuitry
related
to
memory
itself
is
out
of
order)
we
regret that
it
may
be
impossible
to
restore the data.
