Back-Focus Adjusment
Back-Focus is adjusted at the factory to accommodate most standard lenses.
However, at times, slight adjustment to the IK-6550A back-
focus is necessary.
Loosen the Focus Lock Screw. Achieve a clear image by
rotating the focus ring.
Afterwards, tighten the Focus Lock Screw.
This camera supports two types of auto-iris lens: Video-
type and DC (direct drive) types. Connect the auto-iris
connector plug to the IRIS terminal on the side of the
