sensors should not be exposed to laser beam radiation in an environment where a laser
beam device is used.
Phenomena Specific to Image Sensors
The following phenomena that may occur in images are specific to image
sensors. They do not indicate a malfunction.
White flecks
Although the image sensors are produced with high-precision technologies, fine
white flecks may be generated on the screen in rare cases, caused by cosmic rays,
etc.
This is related to the principle of image sensors and is not a malfunction.
The white flecks especially tend to be seen in the following cases:
- when operating at a high environmental temperature
- when you have raised the gain (sensitivity)
- when using the slow shutter
Aliasing
When fine patterns, stripes, or lines are shot, they may appear jagged or flicker.
About the imaging conditions
 When Auto Iris is set to On, resolution may be unsatisfactory. In this case, set
Auto Iris to Off.
 When View-DR is set to On, resolution may be unsatisfactory. In this case, set
View-DR to Off, Auto Iris to Off and shutter speed to Auto (SNC-CH240).
 When using the manual Iris, set View-DR to Off (SNC-CH240).

Rear
 If you find condensation when you open the package, turn on the power after
