Remedial actions
Referring to the on-line help, adjust the White Balance setting and
then try resetting the camera focus again using the Focus Assis-
tant, as described in Adjusting the Camera Focus on page 39.
If you have previously replaced the supplied CS-type lens, you may
have inadvertently installed a C-type lens - without the required
adapter. See also page 42.
To solve this problem, you need more light. The performance of the
camera is best in 100 - 3000 lux.
You may wish to consider replacing the basic lens with a more sen-
sitive lens (Lower F-number), if the lighting in the installation area
cannot be improved.
Open the Display Properties in your desktop and configure your dis-
play to show at least 65000 colors, i.e. at least 16-bit.
Note: Using only 16 or 256 colors on your computer will produce
dithering artifacts in the image.
Referring to the on-line help, adjust the White Balance setting and
then try resetting the camera focus again using the Focus Assis-
tant, as described in Adjusting the Camera Focus on page 39.
If you are using Microsoft Internet Explorer, ensure that ActiveX
has not been disabled. Alternatively, use the Java Applet for view-
ing images.
