Cast a new world


A sophisticated electronic products, which combines mechanical, optical, electronic circuit technology, and only the correct and careful maintenance, can reduce the failure rate of the projector to extend its service life. Proposed home projector users attention to the following aspects: 1, multi-projector set up two power switches, a main power switch, a power switch for the projector lamp. General projector with single-phase 220V AC power (and some foreign countries as l10V), the total power consumption between the 350 ~ 600W. Power plug in the plug when the power is turned off to rL (ie, power = \Dry machine, the order of the subsequent opening of the first electric light bulb opening of the main power switch for 5 seconds or so to figure projected onto the screen. Must first power off the projector lamp, L into standby, after about 90 seconds off the projector dagger main power switch should be used to minimize switching t times the impact of current 【affect the lamp life, we must first shutdown was fan stops and then wait like turn off the power switch, wait 5 minutes to re-open sometimes not immediately light bulb is not the power problem, as long as the projector and a small clock to restart. Attention should be paid to the use of the projector there for wind cooling conditions. The current fear is a more high-temperature polysilicon,[link widoczny dla zalogowanych], the vicinity of the newer models are equipped with temperature sensors, when the Mann filter network is blocked, air poor; the internal temperature will rise rapidly, then the alarm device will cut off the light source immediately power, we must ensure that vents are unblocked and in the filter. When the weather is hot and inside, the fan can be used to help heat dissipation, which spent protecting the projector to extend the use of life to avoid the overheating of the projector automatically by a few, affect the normal use. Vents air inlet and outlet points in its bottom outlet in its real Ningbo - 7ft pole technique technologies technology aspect behind the film, pay attention to the bottom and the bearing surface not so close, and do not in the ventilation hole put anything in order to avoid poor ventilation, the impact of heat; the filter mesh is very fine, very easy to damage, demolition action to light, cleaning, avoid using screwdrivers and other hard objects, the best online and vacuum cleaner dust and debris. 4, strong in the machinery should prevent the collision, compression and vibration. Because earthquakes can cause the displacement of liquid crystal film, when the three of LCD projection convergence,[link widoczny dla zalogowanych], there does not coincide with the phenomenon of RGB colors, while the optical system of lenses, mirrors, distortion or damage will affect the image projection,[link widoczny dla zalogowanych], and zoom will track the impact of the lens is damaged, causing the lens stuck, or even rupture of the lens can not be used. 5, the light source part of the filament light should avoid shock, in turn moving the projector is prohibited under state and prevent the lamp burst, can not stop using it immediately after disconnecting the power,[link widoczny dla zalogowanych], let the machine automatically after cooling down, cooling condition in the machine power off the projector damage is one of the reasons the most common repair. 6, if the projector has been transferred to maximum brightness adjustment, the projected image is still dark, or use the \Available on the remote control \hours. When replacing bulbs, use the provisions of the projector bulb model, and note that the machine has high pressure,[link widoczny dla zalogowanych], to turn off the power after 1 hour, unplug the power supply case, replace the lamp, to from electrical shock or burns. 7, moving the projector must gently, to avoid the body's shock result in the lens injury. Need to carry out regular use of a portable projector, be sure to pay attention to the packaging machine. When carrying the projector can be installed in the soft backpack. In shipping, shipped with the projector as far as possible the original shock when the carton packaging. 8, in use, the projector of self-protection state. Then either open the projector's power is off, the projector will be turned off, all the keys do not work. When the projector is not bad, but due to their own heat, in order to avoid damage resulting from a self-protection status, when asked after a while (about 30 minutes) and then start working, everything will be normal. 9, before use to best position the projector. First, the position to choose the right screen, the screen size according to the projector and screen to determine the distance. By adjusting the height of the projector, horizontal angle, vertical gradient, the level of the curtain and the angle of the projector screen and so on, to get the distorted image. 10, do not let the projector lens directly on the sun to avoid damage to the internal optical system. In addition to the above mentioned issues, also need attention immediately after the cover off the lens cap to keep the projector using the site and stored in good health and the environment. 2004 21111 ◆ 47 ~
