Notes on using this product
● 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.
● Check a combination with the lens
Depending on the lens and lighting you use, an image is reflected as a ghost in the imaging area. However,
this is not because of a fault of the camera.
In addition, depending on the lens you use, the performance of the camera may not be brought out fully due
to deterioration in resolution and brightness in the peripheral area, aberration and others.
Be sure to check a combination with the camera by using the lens and lightning you actually use.
When installing a lens in the camera, make sure carefully that it is not tilted.
In addition, use a mounting screw free from defects and dirt. Otherwise, the camera may be unable to be
removed.
Install a next lens; its dimension of protrusion from bottom of the screw is equal to or less than 10 mm. If a
lens does not stand to this condition, it might not be installed to this camera.
10mm or less
C-mount lens Bottom of
the screw
●Mounting to pedestal
When mounting this product to a pedestal, make sure carefully that lens doesn’t touch with the pedestal.

D4235159A
●Do not expose the camera's image-pickup-plane to sunlight or other intense light directly
Its inner CMOS sensor might be damaged.
● 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.

“This symbol is applicable for EU member states only”
This equipment has been tested and found to comply with the limits for a class A digital device,
pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause harmful interference to radio
communication.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
[Phenomena specific to CMOS sensor]
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 time.
Image shading
The brightness of the upper part of the screen may be different from that of the lower part. Note
that this is a characteristic of a CMOS image sensor and is not a fault.

- If your camera is used in a system where its connectors are subjected to strong repetitive shocks, its connectors are
possible to break down. If you use your camera in such a situation, use an USB3.0 cable with a lock screw, and secure
the camera cable as close as possible to the camera body for avoid physical shock to the camera connector.
- About e-CON cable: In the case that electric-wire is long or thin, input and output voltage may not satisfy specifications
of the camera or your system by voltage drop. Please confirm wires’specifications before use them.
