10. Mounting Bracket Hole – This threaded ¼"-20 hole
is used to mount the camera onto a mounting
bracket or tripod.
11. Function Switches – This compartment houses
switches for camera operation. A switch is in the ON
position if it is positioned toward the front of the
camera. If the position is set toward the back of the
camera, the switch is OFF. The switches include:
•
Iris Adjustment Pot (Potentiometer) – This
control allows the user to adjust the level of the
auto iris when the A/I lens selection switch is set
to DC and a DC lens is mounted on the camera.
The switch should be in the video position when
an auto iris video lens is mounted on the
camera. If a video auto-iris lens is used, this
control has no function.
•
BLC Switch – Multiple backlight compensation
adjustments are available. Except when set to
off, the camera will automatically try to maintain
proper exposure in the specific area even if the
lighting level changes. BLC mode may be
selected manually, off, top, bottom or center.
