the sampling line will be displayed at all times in B mode images, and pressing <M>
will directly enter M mode.
5.4.2 M Mode Parameters
In M mode scanning, the image parameter area in the upper left corner of the screen
displays the real-time parameter values as follows:
Display V 3 IP 6 DR 65 G 45
Parameter M Speed M IP M Dynamic Range M Gain
Parameters that can be adjusted to optimize the M mode image are indicated in the
following.

During M mode imaging, menus for B mode and M mode are displayed in the soft
menu at the same time, use the left/right keys of soft menu controls <4> to switch
between the menus of B mode and M mode.
During M mode scanning, frequency and acoustic power of the probe are
synchronous with that of B mode.
Adjustment of the depth, focus position or TGC to the B mode image will lead to
corresponding changes in M mode image.
Press <Update> to switch between the real-time B and freezing B images.
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
