Tower from falling further.
Gently lower or raise the camera mount by pulling to release the height adjustment knobs and
by raising or lowering the unit until the knobs are in line with the center of the display monitor
(see Figure 3-3). This will produce an optimal viewing angle for participants. Once the Tower

should adjust the heights of the chair and/or chin rest on a participant-to-participant basis.

camera lens into the thread on the Camera Head. If the camera handle hits the Camera
Adapter (for a Fiber Optic Camera), use a Philips screw driver to loosen the screw on the
camera handle slightly (the screw shouldn’t come off the handle completely) and pull the
