Operating Instructions
General Usage
- Prepare Hair: Ensure hair is clean, dry, and detangled before styling.
- Adjust Temperature: Use the temperature control buttons (+ / -) to select the desired heat setting. Recommended temperatures vary by hair type:
- Fine/Damaged Hair: Lower temperatures (e.g., 250-300°F / 120-150°C)

- Curling/Waving: For curls or waves, clamp a section of hair near the roots, rotate the flat iron 180 degrees, and slowly pull it through the hair, maintaining the rotation.
- Repeat: Continue with remaining sections until desired style is achieved.
- Power Off: After use, press and hold the power button until the display turns off. Unplug the appliance from the electrical outlet.
