- In case of continuous electricity, the appliance enters the working mode before the standby state after each power on.
- If the appliance is reconnected to power after an unexpected outage (when the power is off or the power cord is unplugged during normal operation), it will restore to the working state before the power outage.
- Preparation: When powered on for the first time, the display panel flashes for 1 second, then the screen turns off. The appliance is in standby state.[Diagram Description: An illustration shows a power plug being inserted into a wall socket, followed by a depiction of the display panel showing a flash for 1 second.]
