Basic User Manual
6.2.18 B Gain
The B mode gain (2D gain), determines the am plifying factors for the received echoes. The
echoes are amplified with the same gain value regardless of depth. The GAIN knob adjusts
the overall brightness of the 2D image.
Instructions:
 Turn the GAIN knob clockwise t o increase the 2D gain, the ultrasound im age gets
brighter.
 Turn the GAI N knob counterclockwise to decreas e the 2D gain, the ultrasound image gets
darker.
 Open the menu, and use the trackball to select LGC L or LGC R , and then rotate the knob
again to adjust the brightness of the left or right part on the image.
NOTE:
 The gain value is displayed on the top left screen as GN.
 B gain can only be adjusted in real time B mode.
6.2.19 Focus
The focal zone determines the depth range for optimizing the concentration of the ultrasound
beam. Multiple focal zones are possible. The focus identified by a red triangle displays in the
right corner of the image.
If multiple focal zones are present, they are shifted with the same amount of depth.
Instructions:
 Flip downward to shift the focal zones to deeper locations.
 Flip upward to shift the focal zones to shallower locations.
6.2.20 Depth
The depth controls the depth range of the ult rasound image. The system autom atically adjusts
the frame rate (FPS) and acoustic power indices (TI, MI ...) according to the depth.
Instructions:
 Flip upward to dec rease t he depth range of the 2D image and the ultrasound
image is magnified.
