Reset Key
If your calculator should ever “lock up,” press Reset—a small hole
located below the [Set] key—to perform a total reset.
Battery
Your calculator is powered by a single 3-Volt Lithium CR-2032 bat-
tery. This should last upwards of 3,000 hours of actual use. Should
the display become very dim or erratic, replace the battery.
Note: Please use caution when disposing of your old batteries,
as they contain hazardous chemicals.
Changing the Battery
Use a small Phillip’s head screwdriver and unscrew the two (2)
screws on the base of the unit. Carefully remove the lower back
housing. Remove the battery from the clip and replace with a new
battery, with positive side up. Then replace the backplate and re-
attach the screws.
Note: Replacement batteries are available at most discount
or electronics stores.You may also call Calculated Industries
at 1-775-885-4900.
