After you have turned on your curling iron, hold the DOWN arrow for 3 seconds. You will then see zeros across your screen. Choose your desired automatic shut-off time by pressing either the UP or DOWN arrow (from 10 minutes to 120 minutes). Once chosen, wait 3 seconds and—voilà!—you have successfully programmed your automatic shut-off.

To set your digital temperature screen to read Celsius instead of Fahrenheit just hold the UP arrow down for 3 seconds and the temperature will automatically change to read Celsius. Repeat the same step to return to Fahrenheit.
