Unable to charge the HT-AX7 speaker.

Check the following:

• We recommend using the supplied AC adaptor and the USB Type-C cable. If the speaker cannot be charged using the commercially available AC adaptor, replace it with the supplied one and check to see if the issue is resolved.
• Make sure that the USB Type-C cable is firmly connected to the DC IN terminal on the Front speaker.
• For details about how to charge the speaker and about notes on charging, refer to the following Help Guide or articles:
