til signal is regained, or another rate is set manually. If power to the SiteMate is interrupted, you will
need to restart the recipe to return to VR. In the CONVERSION window, enter the conversion rate
as follows: if your recipe (.shp file) is written using the entire number as the desired rate, i.e. 30,000
