Manual shutter speed adjustment
≥Avoid recording under fluorescent light, mercury light or sodium light because the colour 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 noises 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 the extremely bright place, the colour of the screen may change or flickers. If so, adjust the shutter speed manually to 1/50 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.
ªShutter speed range
1/25 to 1/8000 seconds: Tape Recording Mode The shutter speed closer to 1/8000 is faster.
If [AUTO SLW SHTR] is set to [OFF], then the shutter speed will be set between 1/50 and 1/8000.
ªIris/gain value range
CLOSE (Closed), F16, ..., F2.0, OPEN (Opened: F1.8) 0dB, ..., 18dB Value closer to [CLOSE] darken the image. Value closer to [18dB] brighten the image. Values with dB are gain values.
