When the Delta3 & 3Plus turns on the AC switch and does not connect any electrical appliances, you will hear a dada sound inside the device when you are close to the device (10-15cm)

Currently, we have discovered and are solving the problem. We suggest that you turn off the AC output switch in time if you do not need it to avoid the sound. We expect to release a new firmware to fix the problem at the end of September. You can pay attention to the upgrade reminder on the APP. If user feedback still cannot solve the problem, upgrade technical support for processing.
