How to use

Switch on the calculator if it has a power button, or begin using it directly if it activates automatically. Perform calculations using the numeric keypad and function keys as needed.

Replace the battery according to the manufacturer’s guidance when display dimming or unreliable operation occurs.

Keep the calculator in moderate light to allow the solar cells to assist the battery, and avoid prolonged exposure to extreme temperatures or moisture. Clean the metal-coated keypad with a soft, dry cloth to maintain tactile response and appearance.
