Manual shutter speed adjustment

≥Avoid recording under fluorescent light, mercury 

light or sodium light because the color and 
brightness of the playback image may change.

≥If you increase the shutter speed manually, the 

sensitivity lowers and accordingly the gain value 
increases automatically, which may increase 
the noise on the screen.

≥You may see vertical lines of light in the 

playback image of a brightly shining subject or 
highly reflective subject, but this is not a 
malfunction.

≥During normal playback, image movement may 

not look smooth.

≥When recording in an extremely bright place, 

the color of the screen may change or flicker. If 
this happens adjust the shutter speed manually 
to 1/60 or 1/100.

Manual iris/gain adjustment

≥Set the shutter speed before setting the 

aperture (iris/gain) when manually adjusting 
both settings.

≥If the value does not become “OPEN”, you 

cannot adjust the gain value.

≥If the gain value is increased, the noise on the 

screen increases.

≥Depending on the zoom magnification, there are 

iris values that are not displayed.

ª

Shutter speed range

1/60 to 1/8000 seconds: Tape Recording Mode
1/30 to 1/2000 seconds: Card Recording Mode
The shutter speed closer to 1/8000 is faster.

ª

Iris/gain value range

CLOSE (Closed), F16, ..., F2.0,
OPEN (Opened: F1.8) 0dB, ..., 18dB
Value closer to [CLOSE] darkens the image. 
Value closer to [18dB] brightens the image.
Values with dB are gain values.
