The smart board for classroom is already an indispensable tool for modern teaching, but there are often many friends who react that the interactive whiteboard for classroom is not very obedient in the process of use, for example, the handwriting written under normal conditions cannot be displayed, the working status indicator light is not lit, and the "buzzing" sound is emitted when used, so that users are confused.

In fact, users don't have to worry too much about these problems, as long as you usually take more care of "her" in the process of use and operation, coupled with proper maintenance and maintenance, I believe that "she" will not fail. Let's take a look at the basic maintenance matters during the use of the smart board interactive whiteboard.

The first is the maintenance of the electronic whiteboard surface.The board surface is the main part of the electronic whiteboard and an important display part, and its maintenance needs to start from two aspects: daily use and cleaning.

During the use of the whiteboard, it is best not to let anything come into contact with the board except for special pens or writing instruments, because their contact with the whiteboard can produce electronic interference and cause damage to the board surface. This will make it impossible to record some operations on the electronic whiteboard when used in the future. Of course, if it comes into contact with the magnet, it will also make a "buzzing" sound, which will affect the normal use of the whiteboard.

Because the surface of the electronic whiteboard is generally a high-quality wear-resistant material, as long as it is used normally, there will be no problems under normal circumstances, but it is necessary to avoid touching the board surface with sharp objects (such as knives and other sharp things) to avoid destroying and scratching the board surface. In addition, under normal circumstances, do not leave the writing on the board for a long time, as it is easy to make the handwriting unclean. And it is especially important to note that in the process of using the electronic whiteboard, you can not let the oil-based colored pen write on the electronic whiteboard!In case this happens, you must immediately wipe the surface of the electronic whiteboard with absorbent cotton dipped in alcohol.

In order to ensure a good display effect of the board surface, the board surface needs to be cleaned frequently. If the whiteboard is used frequently, it is best to clean it once a week or so so that the best clarity can be maintained. The user is reminded that the electronic whiteboard should first exit the system before cleaning the electronic whiteboard panel. Because when the computer is in another state (e.g., when a program is open or on the desktop), touching the screen can activate the program or mess with the icons. After exiting the system, turn the projector into standby mode, which makes it easier to show stains and streaks. Generally speaking, the cleaning of the writing surface of the electronic whiteboard can be cleaned with a clean soft cloth. Never scrub the screen with a dry cloth to avoid an electrostatic charge. The damp cloth used for scrubbing must be wrung out, so that no water can flow out, and no water can seep into the board from the bottom frame. It can also be used after trying non-abrasive denatured alcohol and glass cleaners in a small area. A special whiteboard cleaner can achieve better cleaning results, and when encountering dirt that is difficult to remove, you can spray the cleaner onto the panel and then wipe it with a paper towel.

And don't worry if stubborn marks appear, users just cover them completely with the ink of a dry-erasable marker pen and then wipe them off with a soft cloth. Dry-wipe inks contain solvents that dissolve permanent inks. If traces of the original permanent ink remain, spray the area with a standard glass cleaner or whiteboard cleaner and wipe it clean.

Note: When wiping dirt, do not use thinner and volatile oil to wipe the whiteboard writing surface, otherwise it may become discolored or damaged; Do not use detergents that contain surfactants, such as furniture cleaners, as this may cause the writing to be inerasible. It is best to check the instructions provided with the whiteboard equipment before cleaning.
