Caloric ETT and Caloric OKN (visual-vestibular interaction) mode, which are used in the caloric test (caloric vestibular stimulation).

In Caloric ETT mode, caloric vestibular stimulation starts as soon as a red circle is displayed for 1 second after 10 seconds. Fix the black circle at the center for 10 seconds after 100 seconds (visual suppression). Instructs to follow a black circle that moves sinusoidally after 115 seconds.
