Make sure the remote control is completely dry before reinserting the batteries and using it again. **

The remote control of a smart TV works by using infrared signals to communicate with the TV. When a button is pressed on the remote, it sends a specific infrared signal that is picked up by a receiver on the TV. The TV then interprets the signal and carries out the corresponding action, such as changing the channel or adjusting the volume. Some smart TVs also come with remotes that use Bluetooth or Wi-Fi to connect to the TV, allowing for more advanced features like voice control and touchpad navigation. **
