Basic Calculator

This is a 12-digit calculator with a sturdy ABS plastic frame, designed for quick and easy calculations. It performs basic arithmetic functions such as addition, subtraction, multiplication, division, and percentage. The calculator includes helpful accessibility features like large keys with extra-large print for people with low vision, and voice playback in English that reads out the numbers and results. It also comes with added functions like alarm, date, and time, making it more convenient to use.

Setting the date is simple. Press the Date/Time button until the display shows the format Date-Month-Year-Week. Then press the MRC/SET button to select the part of the date you want to change—it will start blinking. Use the M+/UP or M-/DOWN buttons to increase or decrease the number. Repeat this for each part until the date is set correctly.

To set the time, press the Date/Time button again until the display shows Hour-Minute-Second-Week. Follow the same steps: press MRC/SET to select the section, then use M+/UP or M-/DOWN to adjust the numbers as needed.

If you want to review your calculations, press the Check button. This lets you go back through the steps, and you can easily correct any mistake you find.
