## Questions & Answers

**Q: How to reset B03S Bluetooth transmitter receiver?**
A: Press and hold the "Bluetooth Pairing" button for about 10 seconds until all LEDs flash twice together

**Q: Why is there no sound when I insert a USB flash drive?**
A: USB only supports audio input and can only be used as an audio source in TX/Bypass mode. And the music files in the USB flash drive must be stored in "wav or mp3" format

**Q: Why is there no sound from the headphones after connecting them to the TV via an optical cable?**
A: When choosing the optical output connection of the TV, you also need to make the following settings on the TV: Sound-Audio Output-PCM. The specific steps can be adjusted according to the TV model

**Q: Why is there still a delay after switching the button"LL/HD" of B03S to "LL"?**
A: To enable aptX Low Lantency, your Bluetooth headphones/speakers must also support aptX Low Lantency, otherwise there is delay due to your Bluetooth headphones. Note: aptx LL is not supported in RX mode
