Click on one of the symbols in order to compare the illumination with the related pattern from the Model Book.
Above and Above and below the illuminated page on the left - framed in black - you will find buttons which enable you to magnify (Zoom in) and to reduce (Zoom out) the picture. If you move the mouse over one of the four smaller buttons in the middle the picture will be moved upwards, downwards, to the left or right. The Internet Explorer does not support the function of the Zoom buttons. Alternativ you may open the context menue by clicking the right mouse button (Win 9x/NT) or by clicking the mouse button during pressing "control" (MacOS) and then click on "Zoom in" and "Zoom out". You can move the enlarged page by hand by pressing the mouse button over the page. If there are instructions for the illuminated page in the Model Book a small icon can be found on the right. Clicking on the icon shows the corresponding pattern from the Model Book.
