Projectors play a very important role in our daily lives, and projectors are often used in school classrooms or corporate meetings. So, what do we need to pay attention to when we use the projector normally? What are the precautions to use when using the projector? Let's take a look at the following.
According to the projector usage habits and common problems that we usually accumulate, we mainly divide into the following situations:
1. Do not install this projector on an unstable surface. Do not place the projector on a swaying car, desk, or table.
2. Do not place the projector in a container containing liquid. Do not place vases, flower pots, cups, cosmetics, liquids (such as water) on top of this projector.
3. Please use the accessories only according to the recommended method. Do not damage, cut, handle or twist the power cord.
4. Press the power type as selected by the projector. If you are unable to confirm, please consult your dealer and local electrical company.
5. Place the projector near a wall socket that is easy to remove the plug.
6. Please insert the grounding three-pin plug of the projector into the properly grounded socket. If you are using a two-pin socket, please replace the electrician with a three-pin socket. Please do not plug or unplug it with wet hands.
7. When plugging and unplugging, please pay special attention to the following operations. Violation of the regulations will cause Mars or fire.
(1) Do not insert the plug into a dusty socket.
(2) Keep the plug in close contact with the socket.
8. Do not overload the power outlet. Overloading the wiring or socket may cause fire or electric leakage.
9. Do not place the projector in a place where the power cord is easily stepped on, otherwise the power cord may be worn.
10. Please clean the plug before pulling it out of the socket, please use a damp cloth to clean, do not use liquid or alcohol cleaner.
11. Do not block the ventilation slots and ventilation openings on the projector cover. The above openings provide the necessary ventilation for the machine to prevent the projector from overheating. Do not place the projector on a sofa, mat or other soft object surface, or in a closed cabinet, unless a good ventilation is ensured.
12. Do not insert anything from the vent into the projector. Do not pour any liquid into the projector.
13. Unplug the projector when you are not using it for a long time.
14. Please do not place the projector and remote control on a heating device or a hot place, such as a car.
15. When the following occurs: Unplug the projector from the wall outlet and ask a professional service person.
(1) When the power cord or plug is damaged or damaged,
(2) If you accidentally put liquid into the projector or the projector is exposed to rain and water,
(3) If you do not operate properly in accordance with the operating procedures, or the performance of the projector is abnormal,
(4) If there is a fall or a disaster in the house.
16. The interior of the mainframe uses many glass products such as lenses and light sources.
If the light source lamp is broken, please pay full attention when handling, to avoid being scratched by debris, and please contact the dealer, especially in the case of ceiling use, when the light source lamp cover is opened, fine glass fragments may fall. Take full care to prevent debris from falling into your eyes or mouth.
17. When using the projector, the material or paper may block the air filter under the projector. Moving anything under the projector will block any objects in the air filter.
18. Please do not remove the projector immediately after use.
Doing so can cause serious burns. Before removing the lamp, turn off the power and wait until the time specified in the instruction manual is fully cooled.
19. Do not damage the projector or subject it to any collision.
20. Do not use the projector after the replacement period has passed. Once the replacement period is exceeded, the likelihood of the projector rupturing increases. When the replacement projector information appears, replace it with a new one as soon as possible.
a. The gas of the silver lamp contains mercury vapor. If the lamp breaks, immediately ventilate the house to prevent gas leaking from the lamp from being blown into the mouth or into contact with the eyes.
b. Do not put the face close to the projector with the projector to avoid the gas leaking from the projector lamp being sucked into the mouth or in contact with the eyes.
c. If the projector lamp is broken, you need to replace it with a new one. Please contact the dealer where you purchased the product or contact the nearest dealer for replacement. The projector lamp is broken and pieces of glass are scattered throughout the projector.
d. Especially in the case of the top-down installation, the small glass fragments may fall off when the projector lamp cover is opened. If you are cleaning the projector yourself or replacing the lamp, take care to prevent debris from falling into your eyes or mouth.
If the lamp breaks, the leaked gas is sucked into the mouth or glass fragments fall into your eyes or mouth, or any other adverse reactions are found, consult your doctor immediately.
21. If there is thunderstorm, please do not touch the power plug. Otherwise, it may cause electric shock.
22. Clean the inside of the projector every two years. Ask your dealer to clean the inside of the projector approximately every two years.
If it has not been cleaned for a long time, dust accumulated inside the projector may cause fire or malfunction. Cleaning is more effective before each wet season (eg rainy season, etc.). Ask your dealer about the details of internal cleaning.
23. If the remote control uses a button-type battery, keep the battery out of the reach of children. If swallowed, the battery can cause suffocation and is very dangerous. Once the battery is swallowed, please ask your doctor for help.
