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
colour 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.
≥ 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 colour or flicker. If so
adjust the shutter speed manually to [1/50] 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.
