		• When keystone correction is carried out, the	value (0)
		projected image will become smaller.
		• If using both horizontal and vertical keystone
		correction, first make the vertical correction and
		then make the horizontal correction in that order.
		• The keystone correction settings are memorized, so
		that if you change the position or angle of the
		projector, you may need to readjust the keystone
		correction settings.
		• If the images become uneven in appearance after
		keystone correction is carried out, decrease the
		Sharpness setting.
		• If you carry out both horizontal and vertical
		keystone correction, the correction range will
		become smaller than it would be if only one type of
		correction was carried out.
