Note 1: Information need not be provided for any formulation of TIS not yielding the maximum value of TIS for that
mode.
Note 2: Information need not be provided regarding TIC for any Transducer Assembly not intended for transcranial or
neonatal cephalic uses.
Note 3: Information on MI and TI need not be provided if the equipment meets both the exemption clauses given in
51.2 aa) and 51.2 dd).
(a)
Intended use does not include cephalic so TIC is not computed.
