Also you need to do a couple of steps with the range wheel. First, manualy drag the wheel to read the maximum (I believe it's clockwise till it can't go any more). Then send this to the TDC. Next, set your AOB to 80 degrees port or starbord, and set the scope to the 10 degree lead angle; ie target approaching from the right, point scope at 10 degrees. Target approaching from the left, point scope at 350 degrees. When this is done, send to TDC again.
I use this method with great results. I have found that obtaining an accurate speed is critical with this method.
