Replacing the Batteries
The calculator takes 4 AAA (LR03) batteries as a main power source and one CR2032 lithium battery for memory backup. When the low battery symbol is displayed, you need
to replace the batteries as soon as possible.
Warning! There is danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type
recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions. Do not mutilate, puncture, or dispose of batteries in fire. The batteries
can burst or explode, releasing hazardous chemicals.
Please install the batteries according to the following procedure:
To install the main batteries:
1. Turn off the calculator.
2. Slide up the battery compartment cover.
3. Remove the old batteries.
4. Insert 4 new AAA (LR03) batteries into the main compartment.
5. Make sure each battery is inserted in the indicated direction.
Follow these steps to install the new backup battery. It is recommended you replace this battery every five years:
1. Turn off the calculator.
2. Remove the back cover of the battery compartment. The lithium battery is located underneath the small square cover located above the AAA
batteries. Carefully remove the cover by sliding the tabs forward to align with the slots and gently lift the cover off.
