The Performance Memory (page 14) 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).

keep
your

data
safe.
¢ Make sure that the batteries loaded in the keyboard never go dead.

replacing
batteries,

sure

connect
the
AC
adaptor
to
supply
power
first.
