Gain*
Rotate the outer ring of the M-Mode button to adjust the M-Mode strip gain.
Increasing the gain will brighten the M-Mode strip, increasing received signals. However,
noise may also be increased.
Priority Press the Priority button to gain access to OLED controls assigned to modes that are ‘ON’
but do not have priority.
• For example, if M-Mode is ON, the OLED controls will reflect M-Mode controls as
the active mode. The user can press the Priority button to toggle to B-Mode
which will change the OLEDs to B-Mode without having to turn off M Mode.
Color M Mode
Color Doppler strip is overlaid on the M Mode strip to provide blood flow and tissue movement
information simultaneously. CM strip is available for Color Doppler Velocity (CDV), Power Doppler
(PD) and Color Tissue Doppler (cTDI).
All probes support Color M Mode.
Basic Procedures for Color M-Mode
1. During regular B mode scanning there are two ways to enable Color M Mode:
a. turn on C-mode; optimize it; and then enter M Mode.
b. enter M Mode; optimize it; and then push the <C> knob to enable Color Doppler.
2. During the scanning process, adjust the sampling line accordingly.
3. Adjust the image parameters to obtain optimized images.
a. Dedicated Color M Mode controls are available on the OLEDs while CM Mode has
priority
b. B Mode and M Mode controls can be accessed by pressing the Priority Key and
toggling to the desired mode.
4. Trackball and Set keys toggle B Mode/Color image live or B Mode/Color +M Strip live while
using a cardiac preset and toggles B Mode/Color image live OR M Strip live when in a non-
Cardiac preset.
5. Perform other operations (e.g. measurement and calculation) if necessary.
6. Exit Color M Mode
c. Press <C> or <M> knob on the control panel to exit Color M Mode
d. Press<B> knob on the control panel to return to B Mode
