Handheld Calculator Battery Replacement

To change batteries, you should first have the replacement batteries at hand (two CR2032 Lithium batteries are required) and a small screwdriver to remove the two screws on the back of the calculator. Make sure you install the new batteries with the same orientation (plus and minus) as the original batteries (this is also shown on a diagram on the inside of the back cover). 

The CR2032 battery is available at Radio Shack stores, camera stores or departments, and other places that sell small batteries.  It is round, about 0.75 inches (19 mm) in diameter and 0.125 inches (3.175 mm) thick.

Click here for detailed Instructions on changing the handheld calculator batteries (instructions are also in the User's Guide).

You may have to configure the calculator after replacing the batteries.

If the calculator still does not work, the calculator and/or card are probably defective and need repair.  The calculator and card should be Returned for Service.
