Consult your TV's user manual for more detailed information. • If you are using a SPDIF/Optical connection, make sure your TV is set to PCM audio output. I hear buzzing or humming. • Ensure all cables and wires are securely connected. • Connect a different source device (TV, Blu-ray player, etc) to see if the buzzing persists. If it does not, the problem may be with the original device. • Connect your device to a different input on the Sound Bar. I want to turn off the auto power down function. • An "Always-On" mode can be enabled by pressing and holding the Power and Vol - buttons on the Sound Bar for 5 seconds. • The Bar can be returned to the Auto Power Down mode by pressing and holding the Power and Vol + buttons on the Sound Bar for 5 seconds.
