Usage Precautions
Handle carefully
Do not drop the equipment or allow it to be subject to strong impact or vibration, as such action may cause
malfunctions. Further, do not damage the connection cable, since this may cause wire breakage.
Environmental operating conditions
Do not use the product in locations where the ambient temperature or humidity exceeds the specifications.
Otherwise, image quality may be degraded or internal components may be adversely affected. In particular, do
not use the product in areas exposed to direct sunlight. Moreover, during shooting under high temperatures,
vertical stripes or white spots (noise) may be produced, depending on the subject or camera conditions (such as
increased gain). However, such phenomena are not malfunctions.
Do not shoot under intense light.
Avoid intense light such as spot lights on part of the screen because it may cause blooming or smears. If intense
light falls on the screen, vertical stripes may appear on the screen, but this is not a malfunction.
Occurrence of moiré
If you shoot thin stripe patterns, moiré patterns (interference fringes) may appear. This is not a malfunction.
Occurrence of noise on the screen
If an intense magnetic or electromagnetic field is generated near the camera or connection cable, noise may be
generated on the screen. If this occurs, move the camera or the cable.
Handling of the protective cap
If the camera is not in use, attach the lens cap to the camera to protect the image pickup surface.
If the equipment is not to be used for a long duration
Turn off power to the camera for safety.
Maintenance
Turn off power to the equipment and wipe it with a dry cloth.
If it becomes severely contaminated, gently wipe the affected areas with a soft cloth dampened with diluted
neutral detergent. Never use alcohol, benzene, thinner, or other chemicals because such chemicals may damage
or discolor the paint and indications.
If the image pickup surface becomes dusty, contaminated, or scratched, consult your sales representative.
Disposal
When disposing of the camera, it may be necessary to disassemble it into separate parts, in accordance with the
laws and regulations of your country and/or municipality concerning environmental contamination.
CMOS sensor characteristics
• Defective pixels
A CMOS image sensor is composed of photo sensor pixels in a square grid array. Due to the characteristics of CMOS
image sensors, over- or under-driving of the pixels results in temporary white or black areas (as if these are noises)
appearing on the screen. This phenomenon, which is not a defect is exacerbated under higher temperatures and long
exposure times.
• Image shading
Under global shutter operation, the brightness of the upper part of the screen may differ from the lower part. However,
this does not mean the CMOS image sensor is defective.
This phenomenon occurs under short exposure times and high illumination.
To counteract this phenomenon, reduce the illumination by setting a longer exposure time, or adjust the lens aperture.
It may be blurred by this phenomenon when fast-moving subject captured.
