Using the Zoom Function
If you wish to see a section of the radar picture in more detail, you can use the
Zoom function to magnify the selected area to twice its size. The enlarged area
is displayed in a quarter-screen Zoom Window in the lower right corner of the
screen. A box in the original radar picture indicates the enlarged area; you can
move this using the context-sensitive cursor, changing the image in the Zoom
Window.
Note: If the area you wish to enlarge is in the quarter of the screen that will be
covered by the Zoom Window, you should offset the centre (see the next section)
to move the area to another part of the screen before selecting Zoom mode.
Note: You cannot use Zoom and Windows at the same time: if you turn one on,
the other is turned off automatically, and restored when the first is turned off
again.
