12.1 Precautions
Personnel not trained in dealing with similar electronic devices should not service this camera.
The camera contains components sensitive to electrostatic discharge. The handling of these
devices should follow the requirements of electrostatic sensitive components.
Do not attempt to disassemble this camera.
Do not expose this camera to rain or moisture.
Do not face this camera towards the sun, extreme bright light or light reflecting objects.
When this camera is not in use, put the supplied lens cap on the lens mount.
Handle this camera with the maximum care.
Operate this camera only from the type of power source indicated on the camera.
Power off the camera before any modification such as changes of jumper and switch settings are
performed.
12.2 Typical CCD Characteristics
The following effects may be observed on images acquired by CCD cameras. They do not indicate
any fault of the CCD camera function, but associate with typical CCD sensor characteristics.
12.2.1 Smear
Due to an excessive bright object such as car lights, the sun or strong reflection, vertical smear
may be visible. This phenomenon is related to the characteristics of the Interline Transfer System
employed in the CCD.
12.2.2 Aliasing
When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged images
may appear.
12.2.3 Blemishes
12.2.3.1.1.1.1 Some pixel defects can occur. This does in general not have an effect
on the practical operation.
12.2.4 Patterned Noise
When the CCD camera captures a dark object at high temperature or is used for long time
integration, fixed pattern noise (shown as bright dots) may appear on the image.
