When powered on, After 5 minutes of inactivity, the screen transitions to display four horizontal lines, indicating it is in standby mode. This helps to minimize power consumption when the rice cooker is not actively in use. An additional 5 minutes of inactivity causes the screen to turn off completely, further reducing power consumption. This feature is part of the device's energy-saving design. To wake up the rice cooker from standby mode or to turn the screen back on, simply press any button on the control panel. This action restores the display and allows you to interact with the cooker as needed.
