How to use

Turn on the calculator and enter numbers using the numeric keypad to perform addition, subtraction, multiplication and division. Use the currency conversion function according to the calculator’s procedure to convert values between currencies—set the desired rate as indicated in the user guide and apply it to entered amounts. For tax calculations, input the tax rate and use the dedicated tax keys to add or subtract tax from a displayed value. The solar cell will contribute to power when ambient light is sufficient; replace the battery only when the display dims or becomes unreliable.

Recommendations

Keep the calculator clean and store it away from extreme temperatures or humidity. Use moderate indoor lighting to maximise solar assistance and replace the battery with the recommended type when necessary. For consistent currency conversion and tax results, verify and update rates before performing multiple calculations.
