How do I use the Coanda smoothing dryer for smoothing?

Rotate the cool tip to select Smoothing mode, then press the dryer against the hair to switch airflow direction. For the contact bar, position it against the head until you hear a click and the hair attracts, then run from root to tip to hide flyaways. The Coanda smoothing dryer is designed for use on dry and straight hair. (Page 6)
