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 autoiris 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.
