The system supports two types of zoom:

Spot Zoom: focuses on processing the image of the selected area and enlarges the image with higher
resolution.
7.4.1. Pan Zoom
Pan Zoom is available on the live or frozen image in B mode and Color mode. Rotate the physical
<Zoom> knob on console to zoom an image.
 Zoom Knob
o Turn the Zoom knob rightwards to make the image bigger.
o Turn the Zoom knob leftwards to make the image smaller, down to normal size.
When in Pan Zoom mode, use the trackball to pan the position of zoomed image, and the left bottom
corner of the display screen displays a live thumbnail of the full image with a green box on it indicating
the currently zoomed area.
The B image remains zoomed after entering other imaging modes.
