5.3. Setting Operating Mode (Mode Button)
Press the "Mode" button to select your preferred operating schedule:

- 24-Hour Mode: Provides continuous aroma diffusion around the clock, ensuring your home stays welcoming and fragrant all day. This mode is also suitable for small businesses that operate continuously.
- Smart Mode: The diffuser includes a light detection sensor. In Smart Mode, the diffuser activates only when the sensor detects sufficient light (daytime) and automatically shuts off when it gets dark (nighttime). This helps save energy and is perfect for creating a quiet environment for relaxation or sleep.
