Page 70
When running in remote mode, tapping the [Traverse] or [Side Shot] button from the Traverse / Sideshot screen will
open the Remote Shot screen.
The Remote Shot screen is identical to the
screen with the addition of a [Take Shot] button that
allows you to trigger the total station to take a shot.
[Take Shot]: After the total station is properly aiming toward the prism, this will trigger the total station to take a shot.
If you are performing a side shot, you will remain in the Remote Shot screen once the shot is completed. If you are
performing a traverse shot, you will return to the
screen when the shot is completed.
