Important Notices
»
Do not use alcohol, cleaning agents, spray lubricants,
Rain-X, or other solvents on the housing or lens port.
Use of an incompatible chemical compound can
damage the plastic or component o-rings, which may
result in leaking.
»
DO NOT over-tighten the Dome Shade Set Screws
or you may damage the shade. Over-tightening is
identified by bending of the shade base away from
the port around each set screw. Slowly tighten the set
screws so they just make contact in the recessed areas
and are snug against the port.
Installation and Use
Installing the Dome Port
1.
If the front of the lens is larger diameter than the inner
diameter of the zoom gear, slide the zoom gear over the
lens with the teeth of the gear towards the front of the
lens. Attach the lens to the camera.
2.
Slide the zoom gear over the lens if not already attached.
Push the zoom gear down until it is flush with the front of
the housing’s port mount.
3.
Remove the neoprene cover from the dome port.
4.
Check that the port sealing surface is clean and free of
debris.
5.
Apply a very thin, even layer of lubricant to the exposed
portion of the housing’s front o-ring and to the lens port
sealing surface. Avoid dry spots or uneven build-up of
lubricant.
6.
Loosen the three securing thumbscrews on the port until
they do not show on the inside of the lens port.
7.
Align the port so that the taller projections on the dome
shade are in the 12 and 6 o’clock positions.
8.
Press the port firmly towards the housing until the base of
the port is almost flush with the housing front. If there is
resistance, remove the port and re-check that the
thumbscrews are loosened and that the o-ring is properly
lubricated.
