5. Operating Instructions
5.1 Basic Operation
- After connecting the power, the LCD display will light up, indicating the device is ready.
- Place your hand or foot into the lamp. The smart sensor will automatically detect it and start the curing process with the last selected timer setting, or a default setting if none was chosen.
- The LCD screen will display a countdown timer.
- When the timer finishes, the light will turn off automatically. Remove your hand or foot.
5.2 Timer Settings
The nail lamp offers four preset timer options:
- 30s: Short curing time, suitable for thin gel polish layers.
- 60s: Standard curing time, suitable for most gel polishes.
- 90s: Longer curing time, suitable for thicker gel polish layers or darker colors.
- 120s (Low Heat Mode): Gradual increase in power to minimize heat sensation, ideal for sensitive nails or builder gels.
To select a timer, press the corresponding button on the top panel (30s, 60s, 90s, 120s). The selected time will be displayed on the LCD screen.

5.3 Switching Display Direction
To change the numeric direction of the LCD display, press and hold the 60-second button for 3 seconds. This can be useful for different user orientations.

5.4 Important Notes on Gel Curing
- It is normal for the base coat and color gel to remain slightly sticky after curing. This stickiness helps subsequent layers adhere firmly.
- The top coat will be fully cured and dry, ensuring a glossy, protective finish.
- Dark-colored gels (e.g., black, deep blue, dark green) may require longer curing times. This is normal due to pigment density.
- Avoid applying gel polish too thickly to prevent discomfort or a burning sensation during curing. Apply in thin, even layers.

6. Maintenance
6.1 Cleaning
- Always unplug the device from the power outlet before cleaning.
- Wipe the exterior of the lamp with a soft, dry cloth.
- For stubborn stains, use a slightly damp cloth with mild soap, then wipe dry immediately.
- The magnetic detachable base can be removed for easier cleaning of the interior.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the surface.
6.2 Storage
Store the nail lamp in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
