Battery Information
The calculator is powered by a single 3-
Volt Lithium CR-2032 battery. This
should last upwards of 1,000 hours of
actual use. Should the display become
very dim or erratic, replace the battery.
WARNING: Please use caution when
disposing of your old
batteries as they contain
hazardous chemicals.
The calculator is designed to shut
itself off after about 8-10 minutes of
non-use. Values in memory or shown
on the display will be cleared. A run-
ning stop-watch/timer will affect this
amount of time.
