Glad it works. With the way it is in the picture the toggle switch on the left with the up and down arrow will adjust you percentage of cross slope. Until you plug in a receiver the other number doesn't matter. I "think" that number is a 1' offset from where a receiver was set. Here's the why. You can run a sonic receiver off a string line, dirt grade, top of curb. Let's say a string line starts over an existing curb, you could set your moldboard on the curb, set up a sonic 2' above it and zero the sonic out on the stringline. The sonic will now carry that side of the blade at that height, and the cross slope will carry the other. Then you can adjust down as needed to sub or rock grade. (in this example you could only go down <2' or you'd be to close to stringline.) One more example cutting a shoulder to depth beside asphalt. You could hang the sonic past the end of the blade, set blade on asphalt, zero it out, put cut in, then the sonic can run off of existing asphalt to cut the exact depth you need. The reset button zero's out the sonic receiver. With a laser the switch on the right with the up and down arrow will move the mast up or down. My mast has 4' of travel. There are a few more features in set up, calibrating and offsets.
