2.6 Installation of the acrylic dome cover
The dome cover has two parts, a metal aluminum ring and a clear acrylic dome. The metal ring has
male fine threads that will allow it to mate with the aluminum cover of the dome mechanism.
Caution should be exercised when handling the clear dome preventing any abrasions or scratches to
the surface as this will affect the optical performance of the camera.
Step 1:
Carefully align the two parts as illustrated in Figure 17. Slowly rotate counterclockwise
until a small click is felt indicating the beginning of the threads.
Step 2:
Slowly start rotating the bottom part (clear acrylic) in a clockwise direction without
forcing the threads as illustrated in Figure 18. It takes approximately three (3) complete rotations to
have a complete seal.

Step 2:
Remove the protection film as
illustrated in Figure 19.
Avoid direct contact with the
acrylic if possible.
