Each time you see one of these patterns, press (and release) the button you have in your
hand. Please place and keep your forehead on the instrument forehead rest. "
"Can you see the black spot in the center of the screen? You must keep looking at the black
spot in the center at all times during the test. "
While looking at the black spot in the center, can you see all four triangles at the edge of the
screen?"
"Are you comfortable?"
"A sample of the test is now running. Please press the button whenever you see a pattern
that flickers, or shimmers, or is striped. You may pause the test by holding down the button,
releasing the button resumes the test. You may blink your eyes whenever you want. A good
time to blink is whenever you press the button. "
"There is a brief flash just before the actual test begins. " [select Start Test Button.] "The test
is beginning now. Please remember to keep looking at the black spot in the center of the
screen at all times during the test. "
