How to Adjust Volume

When working as a Transmitter (Headphones, Speakers; Bluetooth Enabling a TV or an AV Receiver)

• When using Digital Optical: This can ONLY be done if your headphone/speaker supports AVRCP (the pair that came with HT5009 does.) You may either adjust the volume via the "+" and "-" buttons on the transmitter or via the volume adjustment controls on your headphone / speaker.
• When using AUX (3.5mm) or RCA: You may adjust the volume directly via your TV / AV Receiver's remote control. If your headphone / speaker has a built-in volume adjustment system, you may use those as well. 
  If your headphone/speakers supports AVRCP, volume can be either adjusted via the "+" and "-" buttons on the transmitter or via the volume adjustment controls on your headphone / speaker.

When working as a Receiver (Mobile Phones, Tablets, Laptop; Bluetooth Enabling a Speaker)

• You may either use your Mobile Phone / Tablet / Laptop to adjust the volume directly. You may also use the "+" and "-" buttons on the transmitter to achieve the same results.
  
  

When working in Bypass Mode (Wired Connection, between a TV and a Soundbar / Speaker)

• You may use your Soundbar / Speaker's remote control to adjust the external speaker volume, and use the volume adjustment buttons on your Headphones to adjust headphones' volume. The volume buttons on the transmitter does not function under this mode.
