The menu is as below:
9.6.1 Adjusting index error(I.E)
To adjust index error, the system will first ask you to „Aim at
a target F1‟. You may press „ENT‟ to confirm after aiming and the
instrument will measure its horizontal angle automatically. The
HA will be displayed for one second and the system will ask you
to „Aim at a target F2‟. Following the same steps, the instrument
will then calculate the index error and display it.
Now press „ENT‟ to save the index error (calibration done),
otherwise press „ESC‟ to quit (previous I.E remains).

the index error is little.
First, place the instrument as picture shown below with
collimator facing up. This will help screw C to adjust the
inclination of the instrument.
