Sanyo VCC-4374 - Manual (Page 15)

SETTINGS
Electronic iris function setting
Use a manual or fixed iris lens and set the lens aperture to the
shortest F stop. Set the EI/BLC switch to the EI-ON position.
Note:
Please refer to the specifications for dynamic range of the electronic
iris.
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 a manual iris lens.
