## Long description

How to use
Place the CASIO WM-320MT on a stable, level surface within adequate lighting so the solar cell can supplement battery power. Use the numeric keys to enter figures and the function keys to perform calculations: press the arithmetic operation, input the next value and then the equals key to obtain results. Use memory keys to store intermediate values when working through multi-step calculations. Replace the backup battery according to the manufacturer’s guidance when on-screen visibility or operation becomes unreliable.
Usage recommendations
For optimal performance, keep the solar panel free of dust and position the calculator where it receives indirect light during use. Use the calculator on a flat surface and avoid exposing it to extreme temperatures or moisture. When performing repetitive or extended calculations, use the memory functions to reduce input errors and speed up workflows.
