Note
•
If there is no sound output from the Sound Bar main
unit and the LED flashes rapidly, try to activate the PCM
signal output on your TV. PCM is the most common
digital audio format used and ensures compatibility.
Direction for setting up your Sound Bar using an
optical cable
Do not bend or kink the optical cable (SPDIF) as it
is fragile and can easily get damaged and broken.
