2.2.3 INSTALLATION OF THE EYECUPS
To install the eyecups (Figure 2-2):
1. Carefully press the eyecup or eye guard over the end of the eyepiece lens.
2. Rotate the eyecup or eye guard into the proper viewing position. Adjust for the best fit. The
eyecup must seal around your eye, preventing the green light from escaping.
2.2.4 INSTALLATION OF THE DEMIST SHIELDS
To install the demist shield on the eyepiece lens (Figure 2-2):
CAUTION:
If the demist shield needs to be cleaned, refer to Paragraph 3.1.1 for instructions. Do not attempt
to clean the demist shield while it is wet, or with wet lens paper. Doing so will damage the coating.
NOTE:
If inclement conditions are expected (e.g. significant temperature changes, high humidity, etc.),
install the demist shield prior to the mission in order to reduce lens fogging.
1. Carefully remove the eye cup or eye guard.
2. Press the demist shield onto the eyepiece. Be careful not to smudge the eyepiece lens or demist
shield with your fingers or hands.
3. Replace the eyecup or eye guard (see Paragraph 2.2.3).
2.2.5 INSTALLATION OF THE SACRIFICIAL WINDOW
To install the sacrificial window (Figure 2-2):
CAUTION:
If adverse operating conditions (e.g., large amounts of dust or sand) are expected, attach the
sacrificial window prior to the mission to protect the objective lens from damage.
1. If the objective lens cap is in place, remove it.
2. Gently push the sacrificial window onto the objective lens until it stops. Turn the sacrificial
window clockwise until it snaps into place.
