As the most powerful display device in the office today, projectors have been paid more and more attention by enterprises, and more and more enterprises have begun to purchase projector products to help the office. Then, since the projector will definitely involve post-installation and adjustment, it is mainly because some small details are often ignored by consumers during the installation and adjustment process, so I want to remind consumers, but today we The focus is on some details of the hoisting process.
1, the installation of the hanger
The upper part of the hanger is a square frame with eight through holes of 6 mm in diameter. The eight holes are mounting holes for connecting the hanger to the upper fixing member of the ceiling. The distance between the mounting base surface and the ceiling surface depends on whether the projector is hidden inside the ceiling. If hidden inside the top, this distance should be greater than the sum of the height of the hanger after contraction and the height of the projector itself.
2, projector installation
The bottom of the hanger is a fixed universal hanger for the projector. According to the size of the projector, the lever of the universal hanger is adjusted to connect the projector.
3, electrical connection
Connect the power cable and control cable correctly according to the wiring diagram given. The various wires of the projector itself are installed as follows: two wire ropes are respectively sleeved with a plurality of small rings. When the hanger reaches the maximum stroke, the wires of the projector are first fixedly connected with the small ring by the plastic cable tie, and then Down to the upper "Z" form is connected to the two heel wire. When the hanger moves up and down, the various wires of the projector will move between the two wires.
4, adjust the height of the hanger
There are two travel switches on the upper part of the hanger to control the upper and lower positions of the hanger. Loosen the bolts on it and press the mark to move the travel switch left and right to adjust the position of the hanger and then tighten the small bolts.
Note that installation here does not mean that you can use the projector to enjoy the projected image immediately. In order to get better results, we must also adjust it. Because some settings of the projector that you just bought are standard values, the projected effect is not necessarily optimal, so for future use, you must make some adjustments to many parameters.
The first is the resolution adjustment. At present, the most common resolution of the computer is 1024×768. If the projector you choose supports 1024×768 resolution, basically no adjustment is needed, but if you use a projector that supports the highest resolution. It is 800×600, but the resolution set by the computer is 1024×768 or higher. In this case, the projector will automatically display the image with the compression function. Although we can see the image normally, the display quality of the screen is greatly reduced. Therefore, the resolution of the video source should be set according to the resolution supported by the projector to match each other for best results.
Projector tips
After finishing the installation and adjustment, I will send you some tips for using the projector. Because the projector is different from ordinary display products, it needs to be treated more carefully. Finally, we will provide you with several tips for using and protecting the projector.
1. Before turning on the projector, you need to confirm that the projector cable is connected properly, and make sure the video source has been output normally. After completing the projection connection and turning on the projector, you also need to switch the output mode. Because there are three ways to output the projector, you can press and hold the Win logo button and the F5 button (when connected to the notebook, you can press the Fn button and the F8 button) to select the appropriate screen output method.
2. In the eyes of users who are not familiar with the projector, the projector is like an ordinary TV set. If you want to turn it off, it will turn off the power directly. As everyone knows, this kind of operation is to use the "big taboo" of the projector, because the direct shutdown of the projector under long-term use will seriously affect the life of the projector bulb. Proper power-on sequence: Turn on the projector power button first, then press the Lamp button on the projector's operation panel. When the flashing green signal stops flashing, the power-on is completed. Correct shutdown sequence: first press the Lamp button, when the screen appears to be really shutting down, press the Lamp button again, then the green signal light on the projector control panel starts to flash, and wait until the projector's internal cooling fan stops completely. When the green signal stops flashing, turn off the projector and turn off the power. In addition, between each opening and closing operation, it is best to ensure that there is an interval of about 3 minutes, in order to allow the projector to fully dissipate heat. The opening and closing operations are too frequent, which may cause the projector bulb to burst or the internal electrical components of the projector to be damaged.
3. Whether the projector lens is clean or not will directly affect the clarity of the content on the projection screen. When various circles or spots appear on the screen, most of the dust on the projection lens is “causedâ€. At the same time, the projector lens is very delicate. When you are not using it, you need to cover the lens cover to avoid dust. When cleaning, you should use professional lens paper or other professional cleaning agent to remove dust from the projector lens.
