6.6 Removing and Replacing the Lenses
Cautions
• Do not leave the camera unprotected by a lens assembly to minimize dust settling on the sensor surface. • Do not touch optical surfaces. Oil from your hands can permanently damage optical coatings. • Handle the lenses with extreme care. Lenses are breakable and very expensive. • Place unused lens assemblies in a sealed bag or enclosure for dirt protection.
Removing Lens from the System
To remove an installed lens, refer to the follow figures and perform the following steps:
1. Remove the LED ring light that is attached to the lens as follows:
a. Loosen the black knurled nut that holds the electrical cable connector to the main unit and then pull out the cable connector.
b. Pull off the ring light and set it aside. The ring light is magnetized to the lens.
Caution
Use both hands to hold and remove the lens. The lens is spring loaded and will detach from the lens mount with force.
2. With the ring light removed, use both hands to turn the lens a few degrees clockwise, pull it out from its bayonet fitting, and set it aside.
