5. Operating Instructions
- Prepare Hair: Ensure your hair is clean, completely dry, and thoroughly brushed to remove any tangles.
- Power On: Press and hold the power button until the light turns on.
- Select Temperature: Use the '+' and '-' buttons to adjust the temperature to your desired setting. The lights on the side will blink until the selected temperature is reached, then remain solid.
- Lock Temperature: To prevent accidental changes during styling, press the power button twice quickly. A lock symbol will illuminate, indicating the temperature is locked.
- Section Hair: Divide your hair into manageable sections, typically 1-2 inches wide, depending on your hair thickness and desired curl size.
- Curl Hair:
- Open the clamp and place a section of hair between the clamp and the barrel, starting a few inches from the root.
- Close the clamp and wrap the hair around the barrel, away from your face, ensuring the hair lies flat against the barrel. Utilize the cool-touch tip for better control.
- Hold for a few seconds (5-10 seconds, depending on hair type and desired curl intensity).
- Release the clamp and gently slide the curling iron out, allowing the curl to fall naturally.
- Cool Curls: Allow curls to cool completely before touching or styling further. This helps to set the curl and ensure longevity.
- Power Off: Press and hold the power button until the light turns off. Unplug the appliance and allow it to cool before storing.
