If you have trouble when operating your camera, refer to the following. If the guidelines do not
enable you to solve the problem, contact an authorized technician.
The image on the screen is dim.
Check whether the window is stained.
If dirty, clean the lens with a soft and clean cloth.
Picture contrast is weak.
Increase the contrast of the monitor display.
If the camera is being used in an area with very bright lights try moving lens iris, otherwise, shutter
control may be compensating for the light. Always check that the camera is still correctly focused
after it has been moved or adjusted in any way.
The image on the screen is dark.
Increase the brightness of the monitor display.
The image on the screen flickers.
Does the camera face directly into the sun or fluorescent lights?
Change the camera position.
The camera does not work properly and the surface of the camera is hot.
Check your power supply. Make certain that it is regulated. If the distance from the camera to the
power supply is more than 100m then you may need to use a larger supply such as 500mA or 1
amp due to voltage drop over the cable length. We recommend a 500mA or 1 amp supply for all
long distance runs up to 100m.
