8-1 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 during any modification such as changes of jumper and switch setting.

8-2 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 en effect on the practical operation.
Cameras are shipped in the condition that CCD spots are not visible.
In general, it is said that photo diodes of CCD sensor might damage by influence of cosmic ray and as a
result, CCD sensor will have spots.
Please pay attention so that camera might not be influenced by cosmic ray on storage and transportation.
We also recommend to use sea shipment instead of air flight due to strong influence of cosmic ray to
camera.
Pixel defects may be emerged depending on ambient temperature and/or camera settings such as gain up
or long term exposure, and accordingly, the camera should be used within the specifications.
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.
