Advantages
The calculator’s dual power source—solar with button cell backup—optimises reliability by switching to the battery when ambient light is insufficient.

How to use
Place the calculator on a stable surface in adequate light to prioritise solar power. Use the numeric keypad and function keys to enter numbers and perform calculations; results appear on the numeric LCD. When ambient light is low, the calculator will automatically use the internal button cell to maintain operation. Turn off or store the device in a shaded area if long periods of inactivity are expected to conserve the backup battery.
Usage recommendations
For consistent performance, keep the solar panel clean and free from scratches or adhesive residues, and replace the button cell when signs of dimming display or intermittent operation appear. Store the calculator at moderate temperatures and avoid prolonged exposure to direct sunlight to protect the case and internal components.
