The hair curler has two different heat settings and three timer settings for different curl effects and an automatic curl direction for a natural finish. You can basically choose how tight/loose you want the curl by changing the heat and timer settings before you start and the curl alternates left and right each time.
• Setting 8 (8 seconds = 3 beeps) - for loose waves
• Setting 10 (10 seconds = 4 beeps) - for soft curls
• Setting 12 (12 seconds = 5 beeps) - for more defined curls
