Place the diffuser on a flat, stable surface, away from the edge. Carefully remove the plastic outer cover, and fill the reservoir with mineral water (bottled water or tap water, not distilled or deionized water). Do not exeed the maximum water level - 60ml (indicated by the word MAX inside the water tank). Add a few drops of you essential oil or blend of choice (we recommend 6-10 for a room 18-30 square meters). Replace the plastic outer cover on the diffuser, then plug the connecting cable into the Type C jack located on the back of the diffuser. Plug the USB cable into the power supply and push the On/Off button.
One press will give you continuous diffuser with flickering light, two presses will give you continuous diffusion with a steady light, and three presses will give you intermittent diffusion (30 seconds on, 30 seconds off) with a steady light, and four presses will turn both light & diffusion off.
When the water level in the reservoir is low or empty, the diffuser will automatically turn off.
