Not sure what you're on about.. but I'll try to cover the bases. Well, it's a mouse, I see. Wireless. There's a dongle thingy that plugs directly into your USB port. it's the transmitter. The ad is saying it doesnt come with a manual (as if you need one), nor an extension cable, which is only used for convenience so you don't have a bulky transmitter sticking right off the port, that's all.
