Concerning

Backup
I
The

contains
a battery
which
maintanis the contents of
memory
while
the
mam
power
is

The normal
life
of this
battery
is
5 years
or
more, but
it is
strongly
recommended
that
you
change
it
every
5 years as a
nile.
When
it
is
time
to
change the battery,
contact
a
Roland
Service Station.
* The
first
time

^Please
be aware that the contents
of
memory may
at
times
be
lost
;
when
sent
for
repairs or
when by some
chance a
malfimction
has occurred.
Important data should
be saved on
RAM
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
is
may
be impossible to restore
the
data.
