The C-mount adapter ring is used only if a C-mount lens is used on the camera. If a
CS-mount lens is used, the adapter is not necessary. To install the adapter, first screw it into the
lens mount opening on the camera. Then screw the C-mount lens into the adapter.
12. CCD DUST PROTECTIVE CAP
Remove this cap before installing the lens.
Do not handle or leave the camera with cap open.

BACKFOCUS ADJUSTMENT SCREW
This screw is used to position the CCD image sensor at the precise point of focus the
lens.
Backfocusing Fixed-Focal-Length Lenses
1. Install a lens and connect the camera to a monitor and power supply as described in this
manual.
2. Open the iris completely. If an autoiris lens used, reduce the room lighting to allow the lens
to open completely. This gives the most accurate results.
3. Adjust the screw slowly until the sharpest picture is obtained. This completes the
adjustment. The backfocus adjustment screw is held in place by friction, so there is no
locking screw.
Backfocusing Zoom Lenses
1. Install a lens and connect the camera to a monitor and power supply. If the lens is
motorized, it must also be connected to a lens control.
2. Position the camera 25~50 feet (8~16meters) from a flat vertical surface suitable for
focusing. A newspaper works well as a focusing target.
