• LEVEL adjustment

Monitor screen	LEVEL turning direction
Too bright	Counterclockwise (Toward L)
Too dark	Clockwise (Toward H)

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.
