Operation Rotate the “Depth” knob clockwise to increase the depth;
Rotate the “Depth” knob anticlockwise to decrease the depth.
The adjustable depth values vary depending upon the probe types.
Effects Increase the depth to see tissue in deeper locations, while decrease the
depth to see tissue in shallower locations.
Impacts Depth increase will cause a decrease in the frame rate.
TGC
Description The system compensates the signals from deeper tissue by segments to
optimize the image.
There are 8-segment TGC sliders on the control panel corresponding to the
