2. Filling the Water Tank:

   • Lift up the top cover of the diffuser.
   • Fill the water tank with clean tap water up to the 'MAX' line (300ML capacity). Do not overfill.
   • Add 2-3 drops of your preferred essential oil directly into the water tank. Adjust the amount based on desired fragrance intensity.
   • Replace the top cover securely.

3. Connecting Power:

   Insert the USB power cable into the designated port on the diffuser and connect the other end to a 5V USB power source (e.g., a USB wall adapter, computer USB port, or power bank). The device operates on 5V and is not compatible with higher voltage sources like car 12-24V outlets without a suitable adapter.

3. Operating Instructions

The diffuser features mechanical button switches for easy control.

• Power On/Off and Mist Control:

  Press the 'ON' button to start the mist and flame effect. Press again to turn off. The device uses ultrasonic atomization technology for a fine mist.

• Timer Settings:

  Short press the timer button to cycle through the available timing options: 2 hours, 4 hours, or 6 hours of continuous diffusion. The diffuser will automatically shut off once the selected time expires or when the water runs out.

• LED Flame and Atmosphere Lights:

  The diffuser features a realistic LED flame effect with 6 kinds of light effects (including blue and orange light). The light can be set to a constant color, gradient color, or turned off completely. Refer to the specific light control button (often marked 'L' or a light icon) to cycle through these modes.

• Automatic Shut-off:

  For safety, the diffuser is equipped with a water-shortage power-off protection feature. It will automatically turn off when the water level is too low or completely depleted, preventing dry burning.

4. Maintenance

Regular cleaning ensures optimal performance and extends the lifespan of your diffuser.

• Daily Cleaning:

  After each use, empty any remaining water from the tank. Wipe the inside of the water tank with a soft, damp cloth. Do not use harsh detergents or abrasive materials.

• Weekly Deep Cleaning:

  Unplug the diffuser. Use the provided cleaning brush to gently clean the ultrasonic plate (the small ceramic disc at the bottom of the water tank). This helps remove essential oil residue and mineral buildup. You can also use a cotton swab dipped in white vinegar to clean hard-to-reach areas, then rinse thoroughly with clean water.

• Storage:

  If not in use for an extended period, ensure the diffuser is clean and completely dry before storing it in a cool, dry place.

5. Troubleshooting

• No Mist or Low Mist Output:

  • Check if there is enough water in the tank. The diffuser will automatically shut off if water is low.
  • Ensure the top cover is properly seated.
  • Clean the ultrasonic plate with the provided brush to remove any residue that might be blocking mist production.

• Device Not Turning On:

  • Verify that the USB cable is securely connected to both the diffuser and a working 5V power source.
  • Check if the power source (e.g., wall adapter) is functioning correctly.

• Unusual Noise:

  • Ensure the diffuser is placed on a flat, stable surface.
  • Check for any foreign objects in the water tank or near the ultrasonic plate.
  • The device is designed for quiet operation (as low as 29.9dB), so persistent loud noise may indicate an issue.

• Water Leakage:

  • Do not overfill the water tank beyond the 'MAX' line.
  • Ensure the top cover is correctly and tightly closed.
  • Avoid moving the diffuser while it is operating or contains water.
