M Local is the way to shift survey points. Highlight the source point being translated (usually a base point, but it could be a rover point if the rover point was on a known coordinate). Click the chart button below the DPOS button. At the bottom right corner of the screen, you should see a button with two green planes. If you don't see it click on the button at the top left that shows ABS/Known/Auto. Cycle through them until you see the two green planes button. This is the M-Local button. Once selected you will be prompted to give a point or coordinate for the destination of this point. Once selected and okay'ed the point will translate, along with the base point (if it's a rover point) and all rover points collected from that base point. Points observed from other base sessions will not move, nor will any design points. In this regard, it works very much like DPOS in how it translates. Note this is only for small translations such as you might encounter in translating from an autonomous position to a CORS position (a few meters). It is not intended for large translations such as State Plane to 5,000/5,000.
