How do I switch between Wet and Dry mode on the Airstrait?

Use the Mode select button to toggle between Wet and Dry mode. Wet mode is designed for straightening towel-dried hair from wet to dry, while Dry mode should only be used to refresh an existing style. Your hair should be towel-dried and detangled with a brush or comb before use — never use the straightener on dripping wet hair. (Page 4)
