2.4 Radar Display Control Functions
This section describes how to use the radar controls to:
• Use the zoom function to enlarge a selected area.
• Offset the center of the radar display.
• Momentarily hide the ship’s heading marker (SHM).
Using the Zoom Function - SL70MRC Mono Display
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 sec-
tion) 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.

To enlarge an area:
1. Press the
DISPLAY
key. The soft keys are updated.
2. Press the
ZOOM
soft key to toggle the Zoom function ON.
The labels are cleared, and the cursor has control of the zoom box that
indicates the area to be enlarged. This is indicated by the letters
ZMB
in
inverse video, and the four-headed cursor symbol. The zoom box defaults
to its last-used position since power-on.
3. Use the trackpad to move the zoom box to the required area, and press
ENTER
.
The selected area is shown in an enlarged format in the quarter-screen
Zoom window. The original radar picture occupies the rest of the screen.
➤
You can use the context sensitive cursor to select and move the enlarged area
in view in the window (the label
ZMB
is displayed). See Moving and deleting
items with the context-sensitive cursor on page 1-14 .
