7. Maintenance

• Clean the headphones and transmitter with a soft, dry cloth. Do not use liquid cleaners.
• Avoid exposing the devices to extreme temperatures, humidity, or direct sunlight.
• Store the headphones on their charging docks when not in use to ensure they are always ready.

8. Troubleshooting

8.1. No Audio

• Check TV Audio Output: Ensure your TV's audio output is correctly set to "Optical" or "Headphone" as per the connection method.
• PCM Setting: If using Optical, verify that your TV's digital audio format is set to "PCM".
• Cable Connection: Confirm all audio cables are securely connected to both the TV and the transmitter.
• Transmitter Power: Ensure the transmitter is powered on and its indicator light is active.
• Headphone Connection: Confirm headphones are powered on and successfully paired (solid blue indicator light).

8.2. Audio Delay (Lip Sync Issues)

• The HT41899 Plus 2 supports aptX Adaptive and Low Latency technologies to minimize audio delay. Ensure your TV or source device also supports these codecs for optimal performance.
• If connecting directly to a Smart TV via Bluetooth, some TVs may introduce latency. Using the Avantree transmitter with Optical connection is recommended for minimal delay.

8.3. Headphones Not Charging

• Dock Connection: Ensure the charging cables are securely connected to the docks and a power source.
• Headphone Placement: Verify that the headphones are correctly seated on the docks and the charging contacts are aligned.
• Power Source: Try a different USB power source or wall adapter.
