Smart projector use and maintenance tips

There are three common ways to use smart projectors:

1. Use on a fixed plane (tripod or flat)

2. Indoor ceiling hoisting use

3. The projectors that are carried out and used in three different ways have their own characteristics in terms of maintenance.

1. Fixed use: The projector used on the fixed plane at home should pay attention to the connection, so as to avoid the abnormal shutdown caused by accidentally touching the power supply. When the projected picture is tilted or deformed, the legs of the machine can be adjusted and the position can be fixed to make the picture normal; when the machine is working, do not block the ventilation openings, which will affect the heat dissipation of the machine.

2. Hoisting use: Because Smart Projector has the screen inversion function, this function enables the smart projector to be hoisted on the top of the house. The following points should be paid special attention to in the ceiling installation of the projector used in the ceiling installation: Calculate the appropriate distance between the projector and the screen (determined by the size of the screen); The projector lens is on the same horizontal line; the center point of the projector lens and the center point of the projection screen are on the same vertical line; choose a mounting bracket of suitable size; tighten the screws and bolts for installation and fixation in place; adjust the trapezoidal shape of the projected image after installation; Be sure to turn off the power after each use.

3. Portable use: Smart Projector is lightweight and easy to carry and use when going out. The machine is often moved and connected to different input devices. In this case, the following points need attention: When moving the projector over a long distance, be sure to pay attention to the packaging of the machine. When the projector is checked and shipped, try to pack it in the original shock-proof carton; users can carry it with a hard box; when carrying it with you, you can put the projector in a soft backpack; be sure to take it lightly when moving the projector Handle with care to avoid lens damage caused by vibration of the body. During mobile use, pay attention to the possible effects of power supply and different input device performance on the projector.

To ensure the normal operation of the projector, regular inspection and maintenance are essential. For example, for cleaning the ventilation screening program, there are generally slots or openings on the casing of the projector. This is the design for the ventilation of the projector. The air inlet is equipped with an air screening program. When the projector is working, it is used to filter dust. After using for a long time, the slotted gap on the screening program will accumulate dust. In order to ensure the normal operation of the machine, it is necessary to regularly vacuum the opening with a vacuum cleaner. When the machine is working, do not block the ventilation fan. The cleaning and ventilation screening program is especially important for the maintenance of projectors used for ceiling mounting. During engineering installation and subsequent user use, special attention should be paid to dust prevention.
