NOTE
The objective lens focus can be fine tuned after
installation, but in order to obtain an accurate
reading, the compass must be vertical. (The
compass image must be level.)
(1)
Install compass per paragraph 2-10.
(2)
If necessary to more clearly view your distant object,
adjust the objective lens focus slightly by gripping the compass
and turning clockwise.
The compass illuminator can be seen by other
night vision users.
Increase brightness slowly. Excessive brightness
may burn a temporary image into the image
intensifier. Do not increase brightness any more
than is necessary to clearly read the compass
heading.
NOTE
The monocular must be focused at or near infinity
for proper compass operation.
(3)
To view the compass through the goggles, grip the
compass with index finger on top and thumb on illumination button
at the bottom (Figure 2-1). Press button slightly with thumb until
proper brightness is obtained. The image should appear as shown
in Figure 2-29.
