b. Estimate the size of the eyepiece diameter (in mm) and insert that bushing into the NVD mount portion of the adaptor (Fig. 1.1)
c. Loosen the eyepiece thumbscrew (Fig. 1.3) as far as it will go and place the adaptor onto the eyepiece as shown (Fig. 1.2).
d. The end of the eyepiece mount should grab at least a ¼ in of the end of the day/rifle scope to be securely mounted. Tighten the
eyepiece thumbscrew (Fig. 1.3).

body and tighten the NVD thumbscrew. (Fig. 1.6).
Note:
You will be unable to place the daylight cover back onto the
front of the NVD.

1.5) and press together firmly to disengage the lock and
g. Turn on the device. Adjust the objective focus (if applicable) first and then the eyepiece diopter for the best view.
