Specifications

Troubleshooting

• No Audio:
  • Ensure both TX and RX units are powered on and fully charged.
  • Verify that the audio cables are securely connected to the correct input/output ports on both the Avantree Lock units and your audio devices.
  • Check the volume levels on your audio source and connected headphones/speakers.
  • If units become unpaired, press the TX/RX button on each unit to re-initiate pairing.
• Audio Delay (Lip-Sync Issues):
  • Ensure both the TX and RX units are being used together as a set, as aptX Low Latency is most effective when both ends support it.
  • Confirm that your audio source is not introducing its own delay.
• Short Wireless Range:
  • Ensure there are no significant obstructions (walls, large metal objects) between the TX and RX units.
  • Avoid placing units near other wireless devices (Wi-Fi routers, cordless phones) that may cause interference.
