Question about Casio FX-115ES Scientific Calculator
How can i change the battery?
On the back upper right is a cover held in place with a screw. You will need a small screw driver to take off the cover. LR44 battery - one needed
With the new battery it is highly recommended to wife it off with a soft cloth first and then place it into the calculator and replce the cover.
NEXT VERY IMPORTANT press the following buttons to turn on for the first time.
Press "ON" "Shift" "9" "3" "="
This will clear it for use again.
