SETTINGS
C:White balance adjustment
Normally the WB (white balance) switch is
set to the A (automatic) position and the
white balance is adjusted automatically. If a
manual white balance adjustment is
necessary, follow the steps below.
Set the WB switch to the M (manual)
position, then adjust the color.
• Turn R (VR403) to set the red ratio
and/or B (VR402) to set the blue ratio.
D:Electronic iris function setting
Use a manual iris lens or a fixed iris lens
and set the EI/BLC switch to the EI
(electronic iris)-ON position, to engage the
electronic iris function.
Open the lens iris (shortest F stop setting).
The dynamic range of the electronic iris will
be as indicated in table A.
CAUTION:
• The electronic iris is suitable for normal
indoor use. When the EI/BLC switch is
set to the EI-ON position, do not use an
auto-iris lens.
• If used under fluorescent light, the
image may flicker. In such a case,
change to incandescent lighting or set
the EI/BLC switch to the OFF position
and use an auto-iris lens.
• When shooting bright subjects, pay
attention to the light angle in order to
avoid or minimize the smear
phenomenon effect.

When using an auto-iris lens (for
indoor/outdoor use)
Set the EI/BLC switch to the OFF position.
CAUTION:
If conditions are outside the electronic iris
operation range or more than the
maximum illumination, it will cause
saturation of the CCD. In that case, use an
auto-iris lens, and set the EI/BLC switch to
the OFF position.
E: Backlight compensation setting
Use an auto-iris lens and set the EI/BLC
switch to the BLC (backlight compensation)-
ON position, to engage the backlight
compensation function.
A clear picture can be obtained, with the
multi-zone light measuring system.
