Using Zoom
Zoom enlarges all or part of the scrolling bottom display. You can select
automatic zoom so the sounder keeps the bottom in the lower half of the
display window. Alternatively, you can manually pick the area to be zoomed.
➤
To select Zoom:
1. Press the
ZOOM
soft key.
2. Press the
ZOOM ON OFF
soft key to toggle zoom on.
3. Press the
ZOOM FULL SPLT
soft key to toggle between a full window zoom
image or split windows.
If you select split windows, the display is split vertically, with the zoom
image in the left hand window and the scrolling bottom display in the right
hand window. See
Figure 5-9 .
In a split window display, a vertical Zoom Range Bar appears (along the
right hand edge of the scrolling bottom image) that marks the range being
displayed in the zoom window. This bar varies in height with the selected
zoom level. The depths of the upper and lower boundaries of the Zoom
Range Bar are displayed in the upper and lower right corners of the Zoom
window.
