1. Ensure the power is switched OFF before replacing the batteries. 2. Check that each battery is installed with the positive pole facing upwards. 3. Verify that batteries are not damaged or exposed to heat. 4. Securely fasten the back cover with all four screws. 5. Turn the power ON and adjust the contrast as described in the manual. 6. If the device still does not work, reset the memory (this will erase all data). 7. If the issue persists, consult a Casio dealer for hardware problems.

To delete the entire memory on a Casio SF-4000, press the reset button on the back panel. Note that this will erase all stored data.
