The camera has been factory-adjusted to the best position, but it may need to be adjusted according to the object conditions or combination of lenses. If the image is unnatural, adjust it as follows: (Also read the instruction manual of the lens.)

MEMO

If the sensitivity adjustment LEVEL is turned excessively to L, the sensitivity in- creases because of the AGC function of the camera, and the image looks grainy.

If the video iris lens is set to too low a level, malfunction such as the hunting phenom- enon, in which the iris opens or closes unintentionally, may occur.

In such a case, first set LEVEL potentiom- eter on the lens to the H (iris open) posi- tion then adjust it to the optimum level.
