LEVEL adjustment

Monitor screen

LEVEL adjustment direction

 

 

To darken

Anti-clockwise (Towards L)

 

 

To brighten

Clockwise (Towards H)

 

 

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.
