Notes on cable configurations
The presence of lighting equipment and television receivers nearby may result in video and audio
noise. In such cases, change the cable configurations or placement.
Notes on LAN cable connection
Secure the locking screws on the connector manually, and do not use a
driver. Do not secure the screws too tightly. Doing so may wear down the
screw threads on the camera. (Tightening torque: 0.147 Nm or less)
Notes on attaching the lens
Avoiding dust particles
When attaching the lens to the camera, stray dust and other particles may adhere to the sensor
surface and rear surface of the lens. Be careful of the following when attaching the lens.
•
Work in a clean environment.
•
Do not remove the caps from the camera and lens until immediately before you attach the lens.
•
To prevent dust from adhering to surfaces, point the camera and lens downward and do not allow the
lens surface to come into contact with your hands or other objects.
•
Always use a blower brush to remove any dust that adheres.
Never use your hands or cloth, blow with your mouth, or use other methods to remove dust.
Phenomena specific to CMOS image sensors
The following phenomena are known to occur on cameras equipped with CMOS image sensors. These
do not indicate malfunctions.
•
Aliasing
When shooting straight lines, stripes, and similar patterns, vertical aliasing (zigzag distortion) may
appear on the monitor.
•
Blooming
When strong light enters, more than the allowable amount of charge of the sensor element in the
CMOS image sensor (pixel) and the charge is overflowing, enters into the surrounding pixels, and
blooming may occur. However, this does not affect actual operation.
•
Fixed pattern noise
When shooting dark objects in high-temperature conditions, fixed pattern noise may occur
throughout the entire video monitor screen.
•
Defective pixels
Defective pixels (white and black pixels) of the CMOS image sensor are minimized at the factory
according to shipping standards. However, as this phenomenon can be affected by the ambient
temperature, camera settings (e.g., high sensitivity and long exposure), and other factors, be sure to
operate within the camera’s specified operating environment.
