Of
Battery (press

four times)
The
memory
of
each
module
in
the
TX816
is
backed up by
a
Lithium
battery,
so
that
all
voices are protected
when
the
power
is
turned
off,
and
in
the case
of
power
failures.
The
life
of this battery
is
about
five years,
and
the
TF1
is
fitted
with
this
simple
battery
check
device so that
you can
at
anytime check
the
contition of
your
battery.
The
battery
level
is
multiplied
by
a factor of
10 on
the
LED
Display. For
example, the
above
LED
Display
shows
a battery level of 3.5
volts,
indicated
by
the
number
35.
To
leave
this
sub-mode,
press
SW2
or
SW3,
and
the
TF1
will return to the
main
Utility
mode.
SW1
does
not function
in
this
sub-mode.
IMPORTANT:
Once
the battery
level
is
2.2
volts or
less,
the
battery will
need
replacing.
Contact
the store
where you
purchased your
TX81
6
as
soon
as possible.
NOTE:
When
the battery
is
removed,
all
data stored
in
the
memory
will
be
lost.
Be
sure
to
make
a
note
of
any
important parameters before the
battery
is
removed,
so
that
you
can
input
them
again
later.
Better
still,
save
all
the voice
and
function data
on
a
RAM
cartridge or
floppy
disk (as described
in
the
Dump
section
in
this
chapter)
and
load
it
back
into
the TF1
after a
new
battery
is
installed.
