Step 3
"Locking Tab"
To remove the back cover, slide the cover away from
the locking tab towards the bottom of the calculator until
the cover no longer slides.
Then with the front of the calculator facing down, pull
up on the back cover.
The calculator should now be orientated with the front
facing down, as shown in picture 2.
Step 4 - Batteries
The Batteries are now exposed and the
calculator is face down with the back
towards you.
Remove the bottom batteries by pressing the battery
towards you while pulling it out from the far end.
If you can not do the previous step with your
finger try using a flat ended tool such as an
Ipod opening tool.
After the bottom battery has been removed push or
slide the other(top) battery towards you until it is fully
exposed in the battery slot.
Now simply remove the battery.
