Battery
This model uses one (1) CR2016 battery

(included). Should your calculator display

become very dim or erratic, replace the

battery.

Note: Please use caution when disposing of your

old battery, as it contains hazardous chemicals.

Replacement battery is available at most

discount or electronics stores. You may

also call Calculated Industries at

Replacing the Battery
While the calculator is off, turn the

calculator over and use a #1 Phillips screw-

driver to remove the battery holder screw

located near the center at the top. With the

screw removed, pull battery holder out,

remove old battery, and slide new battery

into holder. The negative side of the battery

should be facing you as you insert the

battery holder into the calculator. Replace

screw using a #1 Phillips screwdriver.

Reset
If your calculator should ever “lock up,”

press Reset — a small hole located above

the p key — to perform a total reset.
