While looking into the eyepiece of the polar
alignment scope, adjust the direction of the
mount by turning the altitude adjustment
bolt and azimuth adjustment knobs so that
Polaris comes as close as possible to the
designated position on the reticle.
Set Polaris to the gap between the two segments of the lines
marked 2014 and 2040 adjacent to a mark "POLARIS" as shown
in the figure.

As Polaris shifts to the designated position on the reticle, both
Delta UMi and 51 Cep come close to their own designated
position scales respectively. While looking into the eyepiece of the
polar alignment scope, turn the polar alignment scope body so
that each of the position scale for Delta UMi and 51 Cep come to
the closest to actual Delta UMi and 51 Cep respectively.
The numbers 15 and 40 on the position scales for Delta UMi and
51 Cep show the years 2014 and 2040 respectively.
