How to use

Turn on the calculator and use the numeric keypad and arithmetic keys to perform standard calculations.

When ambient light is sufficient, the solar cell supports operation and reduces battery usage; replace the battery only when the display becomes dim or functions become unreliable. Refer to on-device labels for key positions and basic operational cues.

Usage recommendations

Store the calculator in a protective pocket or sleeve to prevent surface scratches and avoid prolonged exposure to extreme temperatures or moisture. For consistent tax calculations, set the tax rate using the device's tax function before performing multiple related operations.
