Conference dedicated portable HD Video Showcase

Conference dedicated portable HD Video Showcase in multimedia classrooms, often see high-definition video Showcase "shadow", using it with a projector or computer, can effectively improve teaching effectiveness. To ensure high-definition video Showcase efficiently, realistically model, presentations, slides and other objects displayed, the paper summarizes the following special skills, user reference for you. Conference dedicated portable HD Video Showcase 1, to protect the camera, clear display of high-definition video showcase of the most important is the camera optics, HD video showcase through which you can easily work platform individual objects, photographs, slides, etc. clearly displayed. But taking into account the cameras to high-definition video Showcase, including a plastic or polyester rubber component, these things in the face of intense light exposure, it is prone to aging, but also a long time, then the camera imaging results will continue to decline, so likely to influence high-definition video showcase of life. Therefore, in order to ensure efficient imaging camera can, we must take measures to protect the camera HD Video Showcase; for example, do not place the camera at bright light long lines or daylight, and do not work in high-definition video Showcase at high temperatures, especially not high-definition video Showcase from the environment temperature is too low to move immediately after the environment at a temperature too high. In addition, in order to prevent the camera lens surface leave traces, affecting the imaging results, we try to avoid touching the camera lens, but can not make contact with hard objects to the camera. Conference dedicated portable HD Video Showcase 2, the power switch, the correct operation of the power of high-definition video Showcase and off operation, but also have some stress. In general, after the completion of each task demonstrate, not to the rear panel HD Showcase directly off the main power switch turned off, so that high-definition video Showcase will have been affected. Correct operation, the first on the front panel power button is off, then back again panel power button is off. But also in turning on and off, it can not frequently, after frequent switching high-definition video Showcase will affect the life of the built-in light bulbs, and the camera, but also likely to cause micro touch panel switch failure phenomenon occurs. Moreover, to ensure the safety of high-definition video Showcase, we should let high-definition video Showcase inserted into a reliable grounded three-prong outlet; and in not a long time when high-definition video showcase or a thunderstorm, you should promptly HD video Showcase the power to pull out from the outlet. Conference dedicated portable HD Video Showcase 3, each exclusion, eliminate the fault definition video Showcase during the presentation, it is often possible to encounter not display images of the fault, the face of this failure, how quickly we exclude it? In fact, according to a certain order of investigation, you can quickly find the cause of the failure. First, we can see if the camera lens cover is already open, and many people busy in the wrong, in the case has not yet started to open the lens cover demonstration, naturally can not see Demo images; then again check-definition video Showcase and the connection cable between the computer or projector, whether connected correctly, including connection cable access port is properly connected to the cable connector is loose, the connection cables have been damaged and so on their own; in excluding the above factors, then look at high-definition video Showcase telescopic rod there is no adjustment in place, check to see if the camera lens and the object is vertical presentations, in addition to high-definition video Showcase look at ways of working correctly, etc. Conference dedicated portable HD Video Showcase 4, regular maintenance and stay saying goes, "a thousand days to recuperate, temporary use of troops," to get high-definition video Showcase long work efficiently, we should be carefully protected it in peacetime. For example, high-definition video Showcase camera due to the long exposure to the air, it is vulnerable to dust, "attack", if not the dust on the lens surface clean, then, will affect output resolution demo screen, so we should periodically clean the dust on the camera; when cleaning, it should be possible to use a professional cleaning paper, if do not have this kind of professional lens paper, may wish to use to replace what glasses cloth; and when cleaning the dust, you should use Professional camera blower will blow dust on the surface again, and then use the lens paper or glasses cloth to gently wipe remaining dust. In addition to dust the camera lens needs cleaning, high-definition video Showcase working platforms since the area is large, but also directly exposed to the air, so the dust on the surface it will be more, and we need to clean it regularly. When cleaning this type of dust, we should first use a soft brush to clean the dust the work surface again, and then using a soft damp cloth to wipe the table, of course, do not hit the table acidic or alkaline liquid, or will be "disfigured" the. And in order to ensure safety when cleaning high-definition video Showcase, be sure to cut off the power! In addition, when not in use HD video Showcase, please put down its arms, and replace the lens cap; in addition, can not be left unattended other debris on the working platform, particularly those heavy items, it will easily lead to job Platform deformation phenomenon.
