Batteries

Replacing the Batteries: Slide open and
remove the battery door (located on upper
backside of calculator). Remove the old
batteries. Insert two new LR-44 button-cell
batteries, making sure they’re facing posi-
tive-side (+) up. Close the battery door.

Reset

You may at times want to reset your cal-
culator to its factory settings (i.e., reset all
registers and Preference Settings to their
original default values). To do this, turn off
the calculator, hold down the

key, and

then turn it back on.
