The
Performance
Memory
(page
23)
is
electronic
memory,
which
means
that
it
retains
its
contents
even
when
you
switch
power
off,
as
long
as
power
is
supplied
through
the
AC
adaptor
or
by
batteries.
This
means
that
Performance
Memory
contents
will
be
lost
when
there
are
no
batteries
loaded
(or
when
,
the
batteries
go
dead)
and
the
AC
adaptor
is
not
plugged
in
(or
power
through
the
AC
adaptor
is
interrupted
for
any
reason).

the
following
