Using the vertical or swing arm mount, maneuver the colposcope camera into place. Use the function
buttons to zoom, focus, and adjust brightness and color filters.
•
The zoom function is accompanied by auto focus. As you zoom, the camera will adjust its focus
automatically for clarity. If your image is not focusing after zooming, try zooming out and zooming back in.
Adjust the manual focus if needed. If that does not work, you may have to move the camera manually and
adjust the distance between the camera and the object under observation.
•
The camera should be able to rotate smoothly but still stay in place when you let go. If it does not, then the
ball lock and friction knobs may require adjustment. Please reference Chapter 3.
•
Pressing the manual focus button will override the autofocus feature. Once the zoom +/- button is pressed
the camera will begin to autofocus again.
