Replacing the Batteries
Warning! There is a danger of explosion if batteries are incorrectly replaced.
Replace only with the same type of battery or with equivalent batteries (as recom-
mended by the manufacturer). Dispose of used batteries according to the manu-
facturer’s instructions.
• The calculator is powered by two 3-volt CR2032 coin batteries.
• When changing batteries, use only fresh coin-cell batteries. Do not use
rechargeable batteries.
• Do not mutilate, puncture, or dispose of batteries in fire. The batteries can
burst or explode, releasing hazardous chemicals.
• Do not use new and old batteries together, and do not mix batteries of
different types.
1. Have two fresh CR2032 batteries at hand. Only touch the batteries by
their edges. Wipe each battery with a lint-free cloth to remove dirt and oil.
2. Make sure the calculator is off. When changing the batteries, change the
batteries one at a time to avoid clearing the memory. As a back-up, write
down any data that you have stored and might need for later use.
3. Turn the calculator over and pry off the battery cover.
4. Gently remove one battery.
