If using a DC type auto-iris lens, you will need to set the LEVEL
(VR401) volume when shooting in the conditions described below.
L (counterclockwise): To decrease the contrast
H (clockwise): To increase the contrast
• If shooting simultaneously in a dark room
and through a bright window.
• If the subject background is extremely
bright or dark.

monitor is not correct.
Mirror image setting
If the MIR switch is set to the ON position, the image displayed on
the monitor will be reversed horizontally.

back of a truck or bus and looking towards the back, the image will
be as seen in the mirrors.

engage the backlight compensation function.
If using a VIDEO type auto-iris lens
• The ALC volume on the lens should be turned all the way to Av
(Average).

properly for the conditions, set using the LEVEL volume on the
lens.
