Q&A/ Troubleshooting

1. Get noise when playing music?

   – Did you set the “treble” volume to the top? please volume down the “Treble” volume.
   – The gain of BT30D is larger than another model, you can volume down the “Treble” sound. Some speakers are very sensitive so the white noise will be obvious, it’s normal that BT3OD has some noise when you turn up the “Treble” volume.
