Manual Reset

If your calculator should ever freeze or
“lock up,” press Reset - a small hole
located on the back of the calculator. It
is recommended that you use a
straightened paperclip.

Battery Information

Your calculator is powered by a single 3
volt Lithium CR-2032 battery. This should
last upwards of 800 hours of actual use
(1 year plus for most people). Should the
display become dim or erratic, replace
the battery.

WARNING

Because the batteries contain hazardous
chemicals, please use caution when dis-
posing of old batteries. Keep them away
from animals and young children.
