- Night Light Function: The humidifier includes a soothing blue LED light. This light can typically be turned on or off independently or may activate with the humidifier. Refer to the specific button on your unit for night light control. Note that some operational lights may remain illuminated even when the night light feature is off.
- Using Eucalyptus Cold Therapy Sample: If your unit has an aroma tray or specific compartment for additives, place a few drops of the provided Eucalyptus Cold Therapy sample onto the designated pad or area. Do not add directly into the water tank.
- Automatic Shut-off: The humidifier will automatically turn off when the water level in the tank is too low or empty. Refill the tank and restart the unit to continue operation.
