We have a blinking green light on the front of our ear phones. What does that mean and how do we fix it?

A blinking green light on the SIMOLIO SM-823D Pro earphones indicates that no signal is being received. To fix this:

1. Check that all power cords and audio cables are properly connected and functioning.
2. Ensure the TV or audio source is using the correct output port and is working properly.
3. Restart both the base and the headphones.
4. Confirm that both base and headphones show solid green LEDs after reboot.
5. If the base's green LED flashes slowly, check the connection between the base and the TV.
6. Make sure the TV/TV box volume is set to around 30%-40%.
7. Place the transmitter base at least 4 feet away from devices like smart TVs or WiFi routers.
8. Try connecting the base to another compatible audio device if needed.
