4. User Tips
4.1 During setup
4.1.1 In the auto-alignment mode, there is a preview window on the top left corner
of the application window that is used for basic aiming. Sometimes during very
tough situation, there is no or less square nuts shown in the preview window.
This is still OK to go for auto alignment, or you can press F11 to get clear
preview ,since the application is smart enough to correct it, if the scanned
area covers the screen image.
4.1.2 The aiming does not need to be very accurate or perfect; however, the
scanned area should cover the full projection image.
4.1.3 During either auto alignment mode or manual mode, please make sure that
there are no other icons or balloons show up in the application as shown in Fig
20. These icons might impact on the performance of auto alignment.

4.2 During writing and presentation
There are some tips that user needs to pay attention to make the presentation more
enjoyable.
4.2.1 Do not block any of the projected handwriting image by user hands or body.

4.2.2 Leave more room on each side of the screen for presenter, so the presenter
does not need to stay inside the image.
4.2.3 Some of the control icons or tool bars can move to the lower side of screen
image, this can help presenter to have a smooth operation, especially in the
very large screen situation.
4.2.4 For remote sketch or marking, or icon selection, move the red laser spot to the
destination and release the laser button. The cursor will be staying on the
icons or item that you want, and then press the Left1 button as clicking on the
