MOUNTING THE LENS
Rewiring the lens cable in the lens iris plug
1 Prepare the lens cable.
Cut the cable at the plug, then remove approx. 8 mm of the cable sheath and strip about 2 mm from each wire.
2 Install the lens iris plug.
Solder the cable to the pins following the correct pin layout (refer to the table and illustrations), then close
the plug cover.

Flange-back adjustment
If the pick-up surface is not correctly positioned with relation to the lens focal point, the picture will be out of focus
(in particular when using auto-iris power zoom lenses, sold separately). If that is the case, adjust the flange-back
position as described below.
1 Before installing the lens, check that the two flange-back lock screws have been tightened.
If the flange-back lock screws are loose, the CS mount ring will not be secured and it will not be possible to
adjust the flange-back.
2 Fully install the lens, then loosen the two flange-back lock screws.
3 Set the zoom lens to the maximum telephoto position (TELE), then set the focus using the focus ring on the lens.
4 Set the zoom lens to the maximum wide angle position (WIDE), then set the focus by turning the CS mount ring.
5 Repeat steps 3 and 4 until the image stays in focus when changing from a telephoto shot to a wide angle shot.
When the setting is complete, tighten the two flange-back lock screws.
