Step 1: Press and hold the power button until the screen lights up. You can use the power button and the arrow button to adjust the desired settings.
The screen will display many different parameters including time (from 8 to 18sec), loop orientation (R/L) or temperature (from 150 to 200°C).
 
Step 2: Place a strand of hair in the device, then press the oval button up.
Step 3: Hold down the button. Once the beeping starts and the iron stops spinning, release the button and leave the hair in until you hear 2 consecutive quick beeps.
Step 4: Next, remove the wick from the SMOOTHY Curler to release a gorgeous curl achieved in seconds, and with one hand!
