It's a blue tooth receiver ... not a transmitter.

No, bluetooth works between source and output, you have 2 outputs. How would a speaker connect to another speaker? And why?

No special instructions, it should work out of the box with the remote.

Dumb question: have you checked the batteries in the remote?

Good luck with yours, mine lasted a few months then died. I shipped it back to Toshiba for a refund, they wouldn't even send me another unit, just money - which worked out much more to my liking.

You need to turn in the CEC option in your TV settings. Then you need to pair the sound bar with the TV . This is a pretty easy thing to do. You might find the response sluggish when adjusting the volume but if you use the SB remote it will work with better response.

The wireless subwoofer will connect automatically to the soundbar, you may have to press the link button on the back.
