10. Notes
● This equipment achieves 60fps high frame rate for 2 megapixels by employing quad output CCD. It may have some level
difference in brightness between right, left, upper and lower image signals, as each of those signals goes through the different
analog circuit. As the level difference in brightness may increase over time, it is recommended to use the camera readjusting
regularly. Note that the level difference in brightness may be likely to develop especially when the camera is used in high
sensitivity mode (high-gain mode).
● As two or four kinds of image signal are simultaneously output in the multiple output mode(DUAL,QUAD),the projected
pseudo image may happen to occur on the axially opposite image.
● More stable images can be obtained by leaving the equipment for 20 to 30 minutes after power-on.
● A longer exposure time in the pulse width control mode is accompanied by the degradation of S/N ratio due to a decrease in
the dynamic range of CCD, accumulation of thermal noise components of the CCD imaging device in proportion to the shutter
speed. Therefore, it is recommended that the optimum exposure time to be employed is determined after implementing
experiments based on the conditions of the actual operation.
● Refrain from connecting or disconnecting cables and connectors when applying current, otherwise troubles may be caused.
● Fix a lens or implement other measures when using with a large or heavy lens, so that no extraordinarily large force is applied
to the camera.
● This equipment is not allowed to be used for medical purposes, detection of hazardous materials or any other operations of
which performance may exert influence on human lives or safety.
● Do not disassembly this equipment or alter the internal circuits. Accidents such as a fire may be caused by the heat
generation associated with failure in operation.
● Connect this equipment to a high quality power source unit that does not contain noise components.
● Take appropriate measures to control the generation of noise if a power machine or other installations in the close
neighborhood of this equipment radiates noise, which might adversely affect this equipment.
● Do not use this equipment in an environment subject to any temperatures other than that of the specifications or
condensation, or on a place subject to considerable dust or constant vibration/impact.
● When this equipment is not used over a prolonged period of time, isolate the power from the equipment and remove the
power cable and external connection cables.
● When an abnormal or failure condition is detected, immediately stop using this equipment, cut off the power supply, remove
the external connection cables and contact the dealer for inspection/repair.
●
We assume no responsibility whatsoever for any incidental damages (loss of business interests, business interruption,
change in data, loss of data etc.) resulting from the user
’s use of this equipment or performance failure.
● The specifications and operational details described in the catalogues, manuals and others are subject to change for
performance improvement or other reasons without notice.

[Fixing screw for the camera]
[Important]
Beware of a screw length when fixing the camera to a mounting bracket or a metal
plate
at user’s site. The screw length should not exceed the value designated in
“External dimensions” on the end of this document.
If it exceeds the value, there is a possibility that the contents of the camera are broken.
[Important]
On the usage of this equipment, please note the following to prevent the problem of time degradation of CCD image
sensor(Increase of pixel defects etc.).
● Do not use this equipment in an environment subject to high temperatures and high humidity.
Especially in a high-temperature environment, degradation of CCD image sensor is accelerated, and pixel defects such as
sunspot may be caused. It is recommended that the equipment is used in an ambient temperature around normal room
temperature (below 30
℃
degrees) as far as possible. If there is any concern that ambient temperature of the camera may
be heated up when embedded in the apparatus, please consider to use a cooling equipment such as a cooling fan.
● Be careful not to get the light receiving surface be exposed to high intensity light over a long periods of time.
If a right receiving surface is exposed to high intensity light over a long time (regardless of the on/off state of the camera),
the color filter on a surface of CCD image sensor may get discolored or get burnt in and normal image could not be output.
Please reduce the amount of incoming light by using dark filter or by
stopping down the aperture of the lens if the
high
intensity light
like sunlight enters over a long periods of time.
The amount of light falling on the light receiving surface does not decrease with an adjustment of output level by getting
electronic shutter speed higher, therefore note that discoloration or burn-in of image sensor can not be prevented that way.
When this equipment is not used for a long time, it is recommended to store the equipment disconnecting the cable and
fixing a lens cap.
[Important]
It has already been confirmed before shipment that the amount of pixel defects is below a specified level.
However new pixel defect may be generated or the defect level of some pixels may increase over time after shipment according
to inherent nature of image sensor.
Number or level of pixel defect of image sensor may inevitably increase after purchase under natural conditions. However, it
does not arise from structural failure or design failing of the camera.
Therefore, please be aware that such increase of number or level of pixel defect is not covered by warranty.
