„ During Power mode imaging, menus for B mode and Power mode are displayed in
the soft menu at the same time, use the left/right keys of directional soft menu controls
to switch between the menus of B mode and Power mode.
„ In Power mode, acoustic power is synchronous with that of B mode. Adjustment of the
depth or zoom to the B mode image will lead to corresponding changes in Power
mode image.
„ Items that appear in the menu or the soft menus are dependent upon preset, which
can be changed or set through "[Setup] → [Image Preset]"; please refer to "5.13

5.6.3 Power Mode Image Optimization
Power Gain
Description Refers to the overall sensitivity to flow signals, and this function is used to
adjust the gain in Power mode. The real-time gain value is displayed in the
image parameter area in the upper left corner of the screen.
Operation Rotate the <Color> knob clockwise to increase the gain, and anticlockwise
to decrease.
Or adjust it in the image parameter area.
The adjusting range is 0-100.
Effects Increasing the gain will increase the flow signal presented as well as noise,
while the signals may be missing when the gain is adjusted too low.
