Lock on and turn both lines off the center dot is still on the screen Turn lines on and off several times and then turn lines, then turn lock no and off, see the center yellow dot go on and off then clear screen is not working (just removing lines, not dots) Occasionally when you play around a lot with the lines before bringing up the goniometer angles, the goniometer is not reading the correct angles on the angles key in bottom left When we do not have lines on the screen to start, we then pulled up either the hands or targets hit done in secondary toolbar- and the horizontal and vertical lines reappear but we did not have them on to start
