Note:   Do the following when 

adjusting gain while checking 
iris operation.

     

→ Confi rm that the drive unit A/M 

switch is set to [Auto] mode.

     

→  Set the camera iris mode to 

[Auto].

Note:   As you look at the lens iris 

ring, set it to the position of 
maximum gain at which “focus 
hunting” does not occur.

Note:   The current iris gain value 

is retained even if you reset 
other settings as described in 
“3.2.1 Resetting Values.” For 
this reason, you will no longer 
be able to view the default 
setting. If necessary, make 
a note of the default setting 
before adjusting this value.

Your selection is now highlighted.

The display starts blinking.

Press left or right until you reach 
the desired value.

The display changes from blinking to 
highlighted, indicating confi rmation.
