Nano FPK-5010 Soundbar Translation

So on a whim I bought this Nano FPK-5010 Soundbar for my Samsung flatscreen in the bedroom. Problem is the couple of small instruction pages that came with it are only in Thai. 

Connecting the soundbar to the TV was straightforward but I wonder what some of the other buttons are for. Mainly the EQ and Mode buttons?

There is also a small LED display on the front of the soundbar that I can't  understand. When using the soundbar for TV sound the LED displays "LINE" and get audio "Line in Mode" but the other modes I can't understand nor does the LED display make any sense, to me anyway.

Have searched for info on this soundbar on the Internet but can only find places that sell it but nothing about how it operates.

Any help with translation would be really appreciated.

Thanks
