There are 2 adjusting screws. One for up and down. One for left and right. The screw looks like a gear/pinion instead of a normal screw head. You can use a philips screwdriver to adjust. I can't find a picture in google. You try and look for it. If you still can't find it, i try to take a picture of mine tomorrow.
the up-down screw is fairly easy to find. There is a hole that lets you dip a screw driver right in to turn the screw. The left-right one is a bit blocked by wires (in my car).
