To Set A Course - Cammenga PRECISION LENSATIC Instructional Booklet

D. TO SET A COURSE (FOLLOW AN AZIMUTH)
1st Method
1. With the lensatic compass opened wide (fig. 1) and held
level, turn it horizontally until the azimuth is directly under the
black Index Line. Example: you want to follow an azimuth of
120 degrees. Position the Index Line over the 120 degree
mark.
2. Holding the lensatic compass in this position, rotate the
Bezel until the luminous indicator is over the North arrow of
the Dial. The direction indicated by the open compass is the
desired course. As long as the Bezel is not rotated, turning
the open compass so that the Luminous Bezel Indicator is
directly over the North arrow of the Dial can check the course.
2nd Method
1. Turn the fully opened lensatic compass and rotate the
Bezel to align the Luminous Bezel Indicator, the black Index
Line and the North arrow of the Dial.
2. Subtract the number of degrees, in your desired azimuth,
from 360 degrees.
3. Keeping the North arrow under the Index Line, turn the
Luminous Bezel Indicator to this result. Example: you want to
follow a course of 120 degrees. Subtract 120 degrees from
360 degrees, leaving 240 degrees. Keeping the North arrow
under the Index Line, rotate the Bezel until the Luminous
Bezel Indicator is over 240 degrees.
4. Turn the compass until the North arrow lies directly under
the Luminous Bezel Indicator. The direction indicated by the
open case cover points the desired course.
