Electromagnetic IWB features:
1.High anti-interference
Junction EM  Technology interactive whiteboard adopts mature electromagnetic  induction technology.
Signal induction originals are all inside and non-exposed.  It can effectively resist the interference of
the light  in the external environment and the dust in the classroom.
2.Precise orientation and sensitive reaction
Electromagnetic induction technology is also called “Electromagnetic Matrix Positioning Technology”.
Within the whiteboard, it is full of electromagnetic induction coils. It is orientated through the interaction
between the signal sent by Electronic Pen and the induction coils. Due to the short contact distance,
it can be orientated precisely.Without the Location deviation made by Location Technology of long distance,
The whiteboard with Electromagnetic Induction Technology can maintain the handwriting fluent and smooth .
3.Excellent abrasion resistance and high strength structure
Junction EM  Technology interactive whiteboard adopts Polymer Material of high strength and exceptional wear resistance .
It can last for long time. The frame is made of alloy material .It has high strength structure and hard to distort.
Why is the image projected by the projector in the shape of the wrong size or distorted and how to adjust it?
l Check whether the type of the whiteboard set in the driver program complies with that of the whiteboard in use.
l Check whether the whiteboard is correctly located.

If words can be input on only certain areas of the whiteboard, what should I do?
l No. Only special USB cable designed by  Technology can be used to connect the whiteboard and a computer,
due to the unique characteristics of data transmitted.
You should perform Position setting/calibration in the following cases:
l The Interactive whiteboard is installed for the first time.
l The relative locations between the projector and the whiteboard changed.
l The whiteboard driver changed. For example, the driver program is reinstalled or upgraded, and the computer is upgraded.

Can I use common USB lines on the local market to connect the whiteboard and a computer?
In which cases should I perform Position setting/calibration?
l Please insure that the USB cable connected are provided by  Technology, and check whether the USB cable has been connected properly.
l Check whether the Interactive whiteboard works normally. (The indicator of the Interactive Whiteboard can help you to detect, green color
means you’ve got an active working status quo, other wise, please pull out and reconnect the USB cable).
l Check whether COM1 to COM4 serial interfaces are used. The whiteboard has to use one of the serial interfaces.
l Uninstall the ThinkDriver and restart your computer before reinstall it.
l The image is beyond the projection area due to incorrect horizontal or vertical adjustment of the projector.
l The image displayed is incomplete because the resolution of the computer is not set the same as that of the projector.

When the software start, a prompt "Communication with the whiteboard failed. Check that the whiteboard is
correctly connected to the computer". In this case, what should I do?
l You can choose the 25-meter-long USB cable which is one of optional accessories provided by . Technology,
l You can install the special wireless transmission module developed by  Technology and the validity of transmission
distance is from 30 to 100 meters.
l please contact our local reseller or contact us by e-mail to our engineer
l Two types of writing films can be used on the surface of the whiteboard. One type does not support water whiteboard pen,
whereas the other supports. On both types of films, however, writing with oil pens is prohibited.
l In routine cleaning, use clean and damp cloth to scrape the writing film (Note: the damp cloth should be wrung out to
avoid water penetrating inside the whiteboard from the bottom frame).
