The CASIO MJ-12SA features a Two-Way Power system, which operates on solar power and a battery. The display may dim when you are using the calculator in a location that is darker than your nearest dealer.

Important: The battery that comes with the calculator is for initial use only. It is intended to test calculator performance. This calculator is not equipped with an [OFF] switch. Instead, it switches off automatically about six minutes after the last key operation. This is called Auto Power Off. To restore power, press [ON].

Example: Change (20 + 10 – 5) × 2 = 50 to (20 + 10 – 6) × 2 = 48

To review the calculation

• If an error occurs while you are inputting a calculation or editing a calculation, you can press [C] to clear the entire calculation and start again.

• Calculation speed depends on the number of steps accumulated in Calculation Memory.

Your CASIO MJ-12SA calculator has two numeric display formats.

• The CASIO MJ-12SA employs the Indian system of digit grouping. Commas are used to separate digits, making it easier to read large values.

• The MJ-12Da model uses the standard system of digit grouping. Its display uses an apostrophe to separate digits.

You can toggle between these two formats.

You can select one of two different numeric display formats. The following procedure shows how to select a format through the “Setup” screen.

1. Press and hold down [AC] until SET appears.

2. Press [GT] to select the numeric display format. Each press of [GT] toggles between the two available formats. The display shows a sample value in the currently selected format.

3. Repeat step 2 to select the second format. When you press [GT] both formats are shown on the screen.

4. When you are finished, press [AC].

You can toggle between the two numeric display formats by pressing and holding the [AC] key, and then pressing the [GT] key.
