The light of the ordinary projector injures eyes very much
The advantage of the short burnt projector is more obvious
Just because the above-mentioned characteristic, the short burnt projector has just got the general attention of the projector manufacturer in the past two years, have introduced the short burnt projectors of suitable commercial affair and teaching one after another. However, because of the characteristic and needing to hoist the special way to use of the short burnt projector, it is determined that it is different from ordinary projection that the short burnt projector uses in the course. Now we come to talk about using attentive matters of the short burnt projector especially.

The ordinary projectors were mostly adopted (1.7~2.1) : A manual zoom lens, projection is picture of 100 inches, need the distances of projection about 3 meters. And the short burnt projectors are mostly adopted definitely burntly and designed, picture of 100 inches of projection only needs even shorter distance between about 1 meter. So, should fully consider the size of the electronic white board related to it when installing the projector, then choose the corresponding projector, thus position appropriate hoist and mount.
2,Tune-up out of shape of the picture
Because the short burnt projector is matched and basically adopted and hoisted the way with the electronic white board while using, so the projector needs the upset function of the picture, and the regulation out of shape of easier picture. The ordinary projector usually has only vertical trapezoid of the single direction that is corrected, and for convenience users debug the short burnt projection, basically all competence and vertical pair of direction trapezoid are corrected, adjustment picture that so that can be better during installation.
3,Hoist and safeguard
In the course of hoisting the short burnt projector, besides taking size of the electronic white board into consideration in the distance of projection, also need to consider that maintain questions such as the projector,etc. on later stage.
