1. Before mounting a lens, check whether it is CS-mount lens. Dimension (b) of the lens shown in the illustration must be as shown in the table below. If (b) exceeds the value in the table, it may dam- age the inside of the camera or correct mounting may be impos- sible; never use such lenses. The F mark indicates a focal point.

Lens	Flange back (c)	Dimension (b)
CS mount lens	12.5mm	5.5mm or less

*When using the C-mount lens, use the conversion ring (CM46633- 001, MOUNT ADAPTOR).

2.Attach the included ferrite core to the lens cable. Please attach it as close to the camera as possible.

3.Mount the lens on the camera by turning the lens clockwise. Adjust its position.

4.When using an auto-iris lens with an EE amplifier, turn the switch to the “VIDEO” side. When no EE amplifier is equipped, turn the switch to the “DC” side.

5.If the lens has an auto-iris mechanism, connect the lens cable after checking the pin arrangement.

If the lens cable has a different type of plug, use the 4-pin plug. [4-pin plug part no: SCV2859-001]

Contact your dealer of purchase concerning the 4-pin plug.
