How to Fix No Sound on the Skywave X50 Subwoofer？🔥🔥

Please follow these steps to reset and pair:

1. Check that the subwoofer power cable is properly connected and ensure the subwoofer indicator light is functioning normally.
2. Confirm whether the subwoofer indicator light is steady. A steady light indicates a normal connection with the main unit. If the light is blinking, follow the steps below to re-pair:
   a. Press and hold the subwoofer button for more than 5 seconds until it enters fast-blinking pairing mode, then release.
   b. Facing the main unit display, press and hold the “Xupmix” button on the remote for more than 5 seconds until the main unit displays “SUB” to enter pairing mode.
   c. Once pairing is successful, the subwoofer indicator light will remain steady.
3. Power off and restart, or perform a factory reset. 【https://support.ultimea.com/hc/en-us/articles/50917368752281-How-do-I-reset-the-Skywave-X50-to-factory-settings】
   
    

Q1: The subwoofer light is not turning on. What should I do?
A1: Please check the power cable connection of the subwoofer. Ensure it is securely plugged in. If necessary, disconnect and reconnect the power cable to make sure it's properly connected. 
If the problem persists, it may be due to a faulty subwoofer power cord. Please contact our after-sales team for a replacement part.
