Identify TV Audio Output: Check your TV for available audio output ports. The BKM300 transmitter supports USB Audio Out, 3.5mm Audio Out, and RCA (red/white) Audio Out.
Connect the Transmitter:
- For USB Audio Out: Plug the USB transmitter directly into an available USB port on your TV.
- For 3.5mm Audio Out: Connect one end of the 3.5mm audio cable to your TV's 3.5mm audio output jack and the other end to the 3.5mm input on the transmitter. Plug the transmitter's USB connector into a TV USB port for power.
- For RCA Audio Out: Connect the RCA audio cable (red and white plugs) to the corresponding red and white audio output jacks on your TV. Connect the other end to the RCA input on the transmitter. Plug the transmitter's USB connector into a TV USB port for power.
NOTE: If your TV only has an optical output, an additional optical adapter (not included) will be required. Please contact Holdsound support for recommendations.
Power On: Once the transmitter is connected and powered (its indicator light will flash green slowly), turn on your BKM300 headphones.
Automatic Pairing: The headphones and transmitter will automatically pair within 1 second. The indicator light on both devices will turn solid green once connected.

7. Troubleshooting

If you encounter issues with your BKM300 headphones, try the following solutions:

Problem	Possible Solution
No Sound	Ensure the transmitter is properly connected to your TV's audio output and receiving power. Check if the headphones are powered on and paired (solid green light). Increase the volume on both the headphones and your TV. Verify your TV's audio output settings are configured correctly (e.g., external speakers, PCM audio).

Short Wireless Range	Reduce obstacles between the transmitter and headphones (e.g., thick walls, large appliances). Ensure the transmitter is not placed near other wireless devices that may cause interference.
