How to use

Place the calculator on a flat surface with the solar panel exposed to ambient light to optimize power from the solar source. Use the numeric and function keys to enter numbers and perform calculations; memory keys allow storage and recall of intermediate results. When ambient light is insufficient the backup battery automatically supplies power. Clean the keypad and display surface with a soft, dry cloth and avoid exposure to moisture or extreme temperatures.

Recommendations

For reliable operation, keep the solar panel unobstructed and replace the backup battery according to the manufacturer’s guidance when you notice dimming of the display or slower response. Store the calculator in a dry place and avoid dropping or pressing keys excessively to maintain long-term usability.
