Note that the Electronic Pen does not always operate properly when within 50mm (2") of the top of the screen, 100 mm (315 / 16 ") of the position receiver and 35 mm (13/ 8") from the bothsides of the screen.CSince the Electronic Pen position may shift if the image on the screen is trapezoidal, adjust the projectorso that the image on the screen is rectangular.CWhen projecting an image on the electronic print board using a projector, the image on the screen maybecome difficult to see depending on the viewing angle and position due to reflected projector light.If this happens, adjust the location of the projector or change your viewing position.CWhen using a projector to project a PC screen, be sure to use optimum resolution settings for theprojector and the PC. The image may be difficult to see if optimum settings are not used. Fine lines inthe image on the electronic print board screen may appear broken particularly if the projector resolutionis lower than the PC resolution.CWhen using a projector to project images, the Electronic Pen position may shift if the projection positionshifts due to the following causes. If this happens, it becomes necessary to perform calibration to re-position the projected image on the screen. (For details on calibration, please see page 33.)BWhen the installed location of the projector is changed.BWhen the position of the electronic print board is changed.BWhen the projection area and position has changed due to using a projector function such as zoom.BWhen the display resolution of the projector or PC has changed.CNote that the position of an electronic print board attached to a stand may shift if it is struck carelessly.Always make sure the stand's casters are locked in place.CLight from the projector may enter the eye when using a projector to project images for the purpose ofmaking presentations and so on.
