is used to mount the camera onto a mounting
bracket or tripod.
10. 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 – This on/off switch controls
backlight compensation. When set to ON, the
camera will automatically try to maintain proper
exposure in the specific area even if the lighting
level changes.
•
AWB Adjustment – The auto white balance
switch, when set to the AUTO position, allows the
camera to automatically aim to maintain white
objects as white even if the light color changes.
