NOTE 
The video level adjustment for lenses that use a video   
signal type lens, is adjusted using the binding screws on 
the side of the lens as shown in the method below.     
1)  The lens side sensitivity binding adjustment gauge is 

displayed on the light control menu, when the LENS 
SW on the camera back is set to [VIDEO]. 

 
 
 
 
 
 
 
 
 
 
2)  Please do the sensitivity binding on the side of the   

Lens so that the value of video output level gauge 
[Lev] does not drop from the value of reference level 
gauge [Ref]. 

3)  When the value of [Lev] is adjusted to a lower value   

than the value of [Ref] the repetition phenomenon   
(hunting) of the lens iris may occur along automatic 
gain control in the camera. 

 

In the case where there is a strong light source and sunlight in 
the background, the lens iris will close according to the scene 
brightness, causing the desired object in the scene to appear 
dark. This mode is used under such a condition. 
4)  Press the SET button for longer than 2 seconds to display   

the main menu. 

5)  Use the UP and DOWN buttons to shift the cursor to 

“LIGHT CONTROL”, then press the SET button to display   
the light control menu. 

6)  The following menu is displayed.    Push the SET button   

to select “BLC”, when the cursor is in “MODE”. 

 
 
 
 
 
 
 
 
 
 
7)  Shift the cursor to “AREA SELECT” and push the SET   

button to display the detection area(BLC) select menu.
