10.2. 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 during any modification such as changes of jumper and switch setting.

10.3. Typical CCD Characteristics

The following effects may be observed on the video monitor screen. They do not indicate any
fault of the CCD camera, but do associate with typical CCD characteristics.

V. Smear
Due to an excessive bright object such as electric lighting, sun or strong reflection, vertical
smear may be visible on the video monitor screen. This phenomenon is related to the
characteristics of the Interline Transfer System employed in the CCD.

V. Aliasing
When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on
the monitor may appear.


Blemishes
Some pixel defects can occur, but this does not have an effect on the practical operation.

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 white dots) may appear on the video monitor screen.
