Standing from your entrance door, looking up at the awning tube you should see a protrusion at the left end of the tube coming out of a small approx. 1.4 inch grommet (the wiring side). That would be the receiver eye for your remote. If you can see the receiver, your batteries are good and installed properly you may have a defective remote. If you can't see the receiver you may need to attempt to pull it back out of the grommet enough for it to be in line of sight with the remote. I had to do this with mine and I ended up using a small diameter, stiff wire, making a hook to grab it, then needle nose pliers to gently pull it the rest of the way. Be careful not to crush it with the needle nose.
There are also plenty of videos and doc's online if you do a Google search.
