The diffuser is equipped with a visual alarm mode, which causes the device's lights to start flashing and warns that 72 hours have passed. We strongly advise cleaning the tank for hygiene reasons.
Once the diffuser is connected to the power supply (even on first use), the alarm light starts flashing white. Press the - button for 3 seconds to switch off the alarm light. The 72-hour countdown begins. Once the 72 hours have elapsed, the alarm light starts flashing white. The water tank needs to be cleaned. Disconnect the power supply when cleaning the tank.
The countdown continues as long as the diffuser is connected to the power supply. Switching off the diffuser does not affect the elapsed time, and disconnecting the power supply will reset the countdown.
