Connect the camera according to the connection method, turn it on, display an image on the
monitor, and check the image. 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.)
• 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.
