In addition, it uses a single CR2032 lithium battery as a back up power supply for the memory. If the following message appears on the display, immediately stop using the calculator and replace batteries.

Be sure to replace the main batteries at least once every two years, no matter how much you use the calculator during that time. Warning! If you remove both the main power supply and the memory back up batteries at the same time, all memory contents will be erased. If you do remove both batteries, correctly reload them and then perform the reset operation. The batteries that come installed in this unit when you purchase it are for factory test purposes, so they will probably not provide normal service life. k kkkkkReplacing Batteries Precautions: Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the unit. Note the following precautions: • Be sure that the positive (+) and negative (–) poles of each battery are facing in the proper directions. • Never mix batteries of different types. • Never mix old batteries and new ones. • Never leave dead batteries in the battery compartment. • Remove the batteries if you do not plan to use the unit for long periods. • Never try to recharge the batteries supplied with the unit. • Do not expose batteries to direct heat, let them become shorted, or try to take them apart.
