Do not drop, or give a strong shock or vibration to the camera. This may cause problems. Treat
the camera cables carefully to prevent cable problems, such as cable breakdown and loosened
connections.
Operating ambient temperature and humidity.
Do not use the camera in places where temperature and humidity exceed the specifications.
Picture quality will lower and internal parts may be damaged.
Be particularly careful when using in places exposed to direct sunlight. When shooting in hot
places, depending on the conditions of the object and the camera (for example when the gain is
increased), noise in the form of vertical strips or white dots may occur. This is not a
malfunction.
Restriction for the lens combination
This camera might form a ghost to image area depending on the combination of a lens and an
illumination with this camera. But this is not a failure of this camera. Therefore, please check
the combination of the lens and the illumination with this camera when use.
When mounting a lens, take extra caution so that the lens is not tilted, nor does flaw exist at
