Using the Zoom Function - SL70C Color Displays
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. There are two
zoom options:
• Zoom Into - The enlarged area is displayed in a quarter-screen Zoom Win-
dow in the lower right corner of the screen. A box in the original radar pic-
ture indicates the enlarged area; you can move this using the context-
sensitive cursor, thereby 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 center (see the next sec-
tion) to move the area to another part of the screen before selecting Zoom
mode.
• Zoom From - The enlarged area is displayed in the main window, with the
original radar picture in a quarter-screen 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, thereby changing the
zoomed image.
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 latter is turned off
again.
