out
of
the
calculator
Carefully
disconnect
the
wires
that

calculator
ge "=
The
metal
contacts
on
the

pack
(where

in)
are
the
battery
terminals.
Care
should

be
taken
to

any
metal
object
from
coming
into
contact
with
these
terminals
and

one
position.
Then,
place
the

into
the
compartment
so
that
the
small
