Your calculator is powered by a single 3-
Volt Lithium CR-2016 battery. This should
last approximately 800 hours of actual use
(1 year plus for most people). Should the
display become very dim or erratic, replace
the battery. WARNING: Please use cau-
tion when disposing of your old batteries
as they contain hazardous chemicals.

Your calculator is designed to shut itself off
after about 8-12 minutes of non-use.

Note: Values in memory or shown on the display
will be cleared.

Turn the calculator over and open user
guide door located at the top. Pull battery
holder out (top left corner) and turn over.
