Troubleshooting
No Sound

- Ensure the volume is adequately turned up on both the Audikast Plus and your Bluetooth device.
- For Optical connections, confirm your TV's audio output is set to PCM.
- For AUX/RCA connections, ensure your TV's audio output is set to 'Fixed' or 'Non-Variable'.
Cannot Pair
- Make sure both the Audikast Plus and your Bluetooth device are in pairing mode.
- Temporarily disable other nearby Bluetooth devices that might cause interference.
- To reset the Audikast Plus, press and hold the power button for 10 seconds until the LED flashes red and blue alternately. Then, attempt to re-pair.
Audio Lag/Delay
