(a) This index is not required for this operating mode. see section 4.1.3.1. of the Output Display Standard
(NEMA UD-3).
(b) This probe is not intended for transcranial or neonatal cephalic uses.
(c) This formulation for TIS is less than that for an alternate formulation in this mode.
# No data are reported for this operating condition since the global maximum index value is not reported for the
reason listed.
