You can use any setting 1-4 for any patient. Each setting has different pulse frequencies to prevent adaptation in the patient’s body.

The R setting is just for the red light, and the I setting is for infrared. We don’t usually use these separately, there are there to make sure all the bulbs are working. Infrared light cannot be seen by the naked eye, but can be detected if you look at it through a camera lens.
