2.5 OBJECTIVE LENS AND EYEPIECE
Objective Lens
Whenever the WTM is not being used, the objective lens
cover should be fitted over the objective lens to protect it
from possible damage. The objective lens cover should also
be installed when calibrating the WTM (see section 2.9).
Night Adaptive Filter / Demist Shield
When installed, the night adaptive filter / demist shield
prevents the eyepiece from fogging, and reduces
backlighting and loss of night vision in low light
environments. The filter / shield is installed as follows:
1. Place the filter / shield over the eyepiece with the
threaded side down.
2. Carefully turn the filter / shield clockwise to screw it into
the eyepiece assembly.
3. Insert the end of a pen, paper clip, or similar item into one
of the four retaining ring grooves. Rotate the retaining
ring clockwise to tighten.
