4.3 Manual Stimulation
Manual Stimulation allows for simple, manual control of the Photic flash rate, intensity and duration, as shown in
Figure 5 above.
Rate
Use the slider control to vary the repetition rate from 1 Hz to 60 Hz.
Intensity
Use the slider control to vary the intensity over the range 7 (max) to 1 (min) in 7 steps.
Duration
Use the slider control to vary the flash duration from 1 to 10ms.
The Auto function over-rides the selected duration and automatically adjusts the duration depending on the repeti-
tion rate. At low frequencies, the duration is lengthened and at high frequencies it is shortened, according to the
Duty Cycle set (refer below for details). If the Auto function is selected, the Duration control is not accessible.

Click on the ‘>>’ button to start/stop the flash stimulation. The designated keyboard short-cut keys can also be
used to start and stop the flash stimulation (refer to Configuration below). The assigned key is shown in red text
below the ">>" button.
