While looking into the eyepiece of the
polar alignment scope, turn the altitude
adjustment bolt and azimuth adjustment
knobs so that Sigma Octantis comes to the
gap between the two segments of the lines
marked 2014 and 2040.

Repeat the procedures 5 and 6 until Sigma, Tau and Chi Octantis come to the proper locations on the designated position scales respectively.
Tighten the azimuth adjustment knobs at both sides to finish the polar alignment.
As an illustration here, Sigma Octantis is set to the edge of the line on the side of 2014, and both Tau and Chi Octantis are set to the middle of the
curved lines of the position scale at the protruded edge on the side of 15 respectively. (In case of the year 2014)
Set Sigma Octantis to an approximate position that is
corresponding to the year of your observation.
