Place the XLR8 over the area of involvement (AOI). The clinician may choose to (#2) laser over the nerve root (located using the myotome/dermatome chart) or the organ involved (using the Merrick chart).
If systemic place laser over entire spine and then (#2) over the long bones and the thymus.
The initial setting is where I start, but every week (or two) the Hz's can be interchanged as Staph is a problematic pathogen for some.
Consistency is the most important factor when creating protocols.
The EVRL has significant anti-microbial benefits based upon studies validating 405nm diode.
