NEC WT615 사용자 설명서

The WT615 comes with an electronic pen.
The electronic pen works as a USB mouse connected to the projector. See page

The electronic pen and the projector’s sensors can be used to convert your whiteboard into a virtual touchscreen which
allows you to operate your projector’s menu or use the ChalkBoard feature. See “
