8. Troubleshooting
If you encounter issues with your Xvive U3 system, try the following solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound / Intermittent Audio | Low battery on transmitter or receiver; Units not paired; Interference from other 2.4GHz devices; Out of range. | Charge both units; Ensure units are powered on and paired (indicator lights solid blue); Move away from other wireless devices (Wi-Fi routers, other wireless systems); Reduce distance between transmitter and receiver. |
| Distorted Sound | Incorrect mode selected (Mic/Line); Input signal too hot. | Ensure correct mode is selected (Mic for microphones, Line for line-level sources); Reduce the input gain on your mixer or the output level of the source device. |
| Units not pairing | Incorrect channel selected; Interference. | Ensure both units are on the same channel (1-6). Press the channel button on both units until they match. Try a different channel if interference is suspected. |
