When simply confirming the backsight information, if the OK button (green checkmark) is active, you can simply press
Enter or click OK to move on to the active survey screen. If the OK button is grayed out, that means the program has
detected a new occupied point (or the first one of the survey). Then you must click the Backsight screen and take an
angle and/or distance measurement to the backsight.
When configured to robotic total stations, the Tripod icon takes you first to the robotics control screen for quick
adjustments, and then back to more foresights. From there, you can tab to the backsight screen to access all of the
backsight functions, then easily return when you are finished to the Foresight Screen.
 Occupy Point
: You can manually enter the occupied point ID (occupied/setup point) or click the List icon and
select the point from a list of points. You can also choose the point by clicking the Map icon and selecting the
point from the map itself by tapping a specific point. Finally, a third icon offers the ability to occupy a station and
offset on a known horizontal alignment, without knowing a point number.
In the Station/Offset method, you must load a horizontal alignment (centerline) file and then specify a station and offset.
If you click the "store to disk" icon, it will store the station and offset and after clicking OK in this dialog, you will be
prompted for a description, and the next available point will automatically be assigned. If you enter a station and offset
that is equivalent to a known point, that point will populate in the Pt ID field. And if you enter a point in the Pt ID field,
it will confirm to you the station and offset. In road work, this option can be used simply for confirmation of the correct
station and offset for any entered point.
 Instr. Height
: This is the height of the instrument from the center of measurement (typically middle of the lens) to
the tack in the hub,or ground elevation over which the instrument is set. Units for the instrument height will be set
according to the options in Job Settings. The units for the job are displayed (ft, ift or m). If you brought a feet
and inches tape to the field, and you are set in decimal feet units, you can enter the instrument height as 63" (in
which case 5.25 will be computed) or as 5.6.3.8 (5 feet 6 and 3/8", in which case 5.5313 will be computed).
 Backsight point
: Here you enter your backsight point ID, or pick it from a list or from the map itself, using the
