Insert the mounting rod of the CNR4 sensor into the mounting block of
the mounting bracket, making sure the sensor points to the direction of
the arrows marked as “SENSOR” on top of the bracket (see Figure 3-2).
Perform a coarse levelling of the sensor using the bubble level on the
top of the CNR4, and tighten the four screws on top of the mounting
bracket to properly secure the mounting rod so that it does not rotate.
Do not attempt to rotate the instrument using the sensor heads, or
you may damage the sensors; use the mounting rod only.

Perform the fine levelling using the two spring-loaded levelling screws:
one on the front and the other on the back of the bracket.
