3 System Controls

M
A dual-function control that activates one function when the control is
pressed and another function when the control is rotated.
Pressing the M control displays an M-mode cursor in a 2D image. You can
then roll the trackball to place the cursor in the area of interest. Pressing M
a second time displays 2D/M-mode.
Rotating the M control changes the overall gain M-mode. Rotating the
M control clockwise increases the gain, and counterclockwise rotation
decreases the gain. The range for gain settings is from 0 dB to 40 dB.
When combined with the DGC controls, a gain range of –15 dB to 55 dB
is possible.
M: 35/ 2/

Gain (dB) is indicated by the shaded value.
The gain value displays as the third number in the Image Parameter area for
M-mode, at the bottom of the image screen.
L/R
Changes the scan direction of the active transducer. The image can be
acquired from right-to-left or left-to-right.
The location of the active image indicator defines the direction of scanning.
Rotate
Changes the vertical orientation of the image on the screen. The
ROTATE key causes the image to rotate 90q clockwise with each press of
the key.
3D/4D
Activates the 3D (3-Scape) imaging option.
Note: Only systems shipped with software version 2.0 or higher have the 3D/4D label on
the overlay. Systems shipped with software versions below 2.0 have the 3D label on
the overlay.
