After the connection is complete, turn on the camera, display an image on the monitor and check the video image.

In the case of an automatic iris control lens, the camera has been factory- adjusted to the best position, but it may need to be adjusted according to the condition of the object or the lens combination. If the image is unnatural, adjust it.

Also read the instruction manual of the lens.

Memo:

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

Depending on the lens used, if the LEVEL dial is turned excessively to L, the hunting phenomenon (floppy screen) where the iris opens and closes involuntarily may occur. In such a case, first set the LEVEL dial to the H position, and then readjust the LEVEL dial while checking the video signal.

To adjust the focus accurately, open the lens iris. Below is how to open the lens iris for automatic iris lens.

Press the [SELECTOR] switch on the back panel up (J) for 1 second. [FOCUS ADJUST MODE] is displayed on the monitor screen.

When the focus adjustment is completed, press either [SELECTOR] switch (J, K, H, K), [MENU] or [SET] button.

[FOCUS ADJUST MODE] display disappears and the lens iris returns to original state.

Connect the monitor TV to the VIDEO OUT terminal on the back panel and make adjustments.
