Recording
B Iris/Gain value:
CLOSE # (F16 to F2.0) # OPEN # (0dB to
18dB)
≥Value closer to [CLOSE] darken the image.
≥Value closer to [18dB] brighten the image.
≥When the iris value is adjusted to brighter than
[OPEN], it changes to the gain value.
To restore to automatic adjustment
Set the AUTO/MANUAL/FOCUS switch to
AUTO.
≥When setting both the shutter speed and the
iris/gain value, set the shutter speed and then
set the iris/gain value.
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
gain value will increase automatically
depending on how much the sensitivity lowers
and the noise on the screen may increase.
≥When recording still pictures, we recommend
setting the shutter speed to 1/500 or less for
even more beautiful pictures.
≥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 screen may change color or flicker. If so
adjust the shutter speed manually to [1/60] or
[1/100].
Manual iris/gain adjustment
≥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.
