Values On/Off. See Chapter 17 for probe availability. `CHI' appears next

presettable by frequency to their preset values for the current
harmonic frequency.
Multi frequency values are returned to the factory or user preset

Application, or New Patient.
Benefits Coded Harmonics diminishes low frequency high amplitude
noise and improves imaging technically difficult patients. Coded
Harmonics may be especially beneficial when imaging isoechoic
lesions in shallow-depth anatomy in the breast, liver, and hard-
to-visualize fetal anatomy. Coded Harmonics may improve B-
Mode image quality without introducing a contrast agent.
Bioeffects Activating multi frequency mode may change the TI and/or MI.
