How to use

Place the calculator on a flat surface within sufficient light to allow the solar panel to contribute to power. Turn it on if a power key is present, then enter numbers and operations using the numeric and function keys. Use memory keys to store and recall temporary values when performing multi-step calculations. If the solar supply is insufficient, the internal battery automatically provides power to maintain operation. Clean the surface gently with a dry or slightly damp cloth when needed, avoiding liquids entering the device.

Usage recommendations

For reliable daily operation, keep the solar panel free of dust and position the calculator so ambient light reaches the panel. Replace the battery according to the manufacturer’s guidance when display dimming or intermittent power occurs. Avoid exposing the calculator to extreme temperatures or moisture to preserve keypad responsiveness and display clarity.
