NOTE: The declination offsetting mechanism is set at zero at the factory. Use the
zero setting for all compass operations which involve no allowance for declination
or in which the temporary allowance is being used. If the declination scale does
not read zero, set it to zero with the adjusting screw.
NOTE: When the orienting arrow is not set at zero, it becomes obvious that the
orienting lines and the orienting arrow serve different purposes. The orienting lines
are used to line up with orienting lines on the map. The orienting arrow is used to
line up with the magnetic needle when using compass in the field.

Section F
A
“bearing” is the direction or the degree reading from one object to another. One
of those objects is usually YOU. To “take” a bearing means to DETERMINE the
direction from one object to another.
1. Bearings are taken from a map as in Sect. D. The “bearing” is the degree reading
indicated at the index pointer.
2. Bearings can be taken on the terrain, by reversing the steps in Sect. B and C.
When using the compass without the sight, open the cover wide and hold it
level, at waist high, in front of you. The sight and sighting line should be pointing
straight ahead of you. The sighting line acts as a pointer. Pivot yourself and com-
pass together until the sighting line points straight to the object on which you
are taking the bearing. Without changing position of the compass, carefully turn
the dial until the orienting arrow and the magnetic needle are lined up and with
