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 flange-back lock screws.
