BSS:
In the second interface , press [F2] to enter the
interface of input the coordinates of backsight (as
shown in picture below).Setting up “BBS” is to
establish the relationship between the earth coordinate
and x coordinate of instrument (being used together
with “ STA” Function). After setting the “BSS” and
pressing ‘ENT’,you need to aim at backsight point.
After pressing [ENT], the instrument will calculate the
azimuth angle of the backsight point, which is
displayed in the HA (horizontal angle) column. The
coordinate of the instrument is now related to that of
the earth station, which is called as ‘set station’).In
order to avoid repeated operation, please first operate
the function of ‘STA’ (‘Station’) then set the BBS and
orient. When orientation, please aim at the BS (target)
precisely. Orientation can be done with [0set], [Hset]
and [Hold] under Angle Mode. If the orientation is
