●This camera is set to CS-mount lens before shipment. To use a C-mount lens, loosen the back focus locking screw with a screwdriver, turn the back focus adjustment ring with your finger or the screwdriver and change the mounting method.

●For the dimension (a) of the lens mounting section as illustrated in the diagram, use the value that is shown in the table below.

●Never use one that exceeds the dimension (a) as it will damage the inner part of the camera and will not allow normal installation. This will result in a malfunction.
