IMAGE] to open a menu with these options:
Spectral Compression Selects Low, Medium, or High.
Low increases the Dynamic Range and displays more
shades of gray; High decreases the Dynamic Range and dis-
plays fewer shades of gray; Medium falls in between.
Transmit Power Controls the maximum acoustic output of
the transducer. Settings range from 5% to 100% of maximum.
Use the lowest setting consistent with diagnostic quality. The
current mechanical index (
MI) and thermal index (TI) of the
acoustic output setting are displayed with the System Data.

manual, and the AIUM document provided with your system “Medi-
cal Ultrasound Safety” for important information about Acoustic Out-
put.
