What to do if the remote control of the Mijia Air Conditioner Pro Eco 3.5 kW is not working or buttons are unresponsive?

If the remote control of the Mijia Air Conditioner Pro Eco 3.5 kW is not working or its buttons are unresponsive, please follow these steps:
1. Check whether the remote control batteries have sufficient power. Replace them if needed;
2. If the issue persists, try restarting the air conditioner by turning off the power and then turning it back on;
3. Check the surrounding environment for possible signal interference. Devices such as routers or high-power appliances placed nearby can affect signal transmission;
4. After installing new batteries, press and hold a button on the remote control. Use your phone’s camera to observe the front of the remote. If you can see a red flashing dot through the camera, it indicates that the remote is transmitting a signal;
5. If the problem still cannot be resolved, please request after-sales service for inspection.
