Operation Manual

 Baseline

Press the ‘ / ‘ buttons of Baseline to adjust the baseline. In Color Doppler mode, the color bar

indicates the direction and speed of blood ow. Based on the baseline at the middle, red indicates

the direction and speed of blood ow toward the probe. By contrast, the blue color indicates the

direction and speed of blood ow away from the probe.

 Line Density

Select the density of scan lines. Tapping the touch screen button incrementally changes the line

density.

Selecting higher line density increases the number of scan lines, resulting in higher image

resolution at the expense of lower frame rate.

 Balance

Use the Balance button’s ‘-/+’ buttons to select the Balance value. The range of a color image

is adjusted by comparing the gray levels of 2D images with the Doppler signal values of color

images. When the Balance value increases, the color image also appears in the part where the gray

level of a 2D image is high (the bright part), increasing the range of the color image.

 Invert

Tap Invert on the touch screen. Tapping the button inverts the color bar; inverting the color bar

also inverts the color displayed on screen.
