Lower the camera for higher magnification; raise it to
reduce the magnification.
Use the lowest magnification you are comfortable
with because:
∑ It is easier to locate your position on the page;
∑ There is less need to move a book on the table;
∑ The focus will work over a greater depth.
Focus
If you change the height of the camera, or if the
thickness of the material being read is changed, you
will need to re-focus the camera. Rotate the focus
control on the top of the Prisma until the image is at
its sharpest. The direction of rotation is unimportant.
Brightness Control
Located under the top hinge, this control adjusts the
image to accommodate extreme lighting conditions
so that the text does not fade into the background
when moving.
