How does a tablet / iPad fit in to the device holder?

The adjustment part on the top of the stand has a little thumb screw adjustment to rotate the head of the camera holder in any direction, including sideways if you want to put a larger device in to hold it sideways.  Just press the thumb screw inward and you can slide the camera holder out to a wider setting. Devices should be in portrait (vertical) position to view the classes as well as to feed the camera image back to FLOE in an upright position.  The device holder has a release button on the top for extending the width of the clamps.  You also need to push this button when closing the device back to the smaller clamp position.  The device holder can accommodate tablets up to an 11-inch screen size or 18cm in device width.
