BACK FOCAL LENGTH ADJUSTMENT
The camera has been factory-adjusted for the proper back focal length using a standard CS
Mount lens. However, when the lens is mounted, it may be necessary to readjust back focal
length to match the lens being used.
CAUTION :
If the back focus locking screw is tightened too strong, the thread section of "Lens Mount"
may be damaged. To tighten the back focus locking screw, use a 1.5 mm ALLEN WRENCH.
Hold the short side of the handle (as shown in Fig.4), and turn it clockwise lightly to the stop
position. Turn a littlemore (approx. 15 degrees) from this position.
For zoom lens:
1. With the camera in operation, view an object at least 70 feet (25 m) away.
2. Make sure the lens iris is wide open.
3. Set LENS FOCUS to FAR position.
4. Adjust lens ZOOM to WIDE angle. (Wide field of view)
5. Loosen the back focus lock screw at the side of the camera using a 1.5 mm ALLEN WRENCH.
Turn the lens mount to obtain the sharpest image on the monitor.
Then tighten the back focus locking screw clockwise. (See Fig.1 for location.)
6. Move lens ZOOM to TELEPHOTO. (Smallest field of view)
7. Adjust LENS FOCUS (by the controller) for best picture.
