Switching Between Horizontal and
Vertical Scan Modes
The Twinscope's scanning mode can only be changed
when you are in the Control Center Menu as shown at
left.
Notice that the display above the first softkey on the left
is split into an upper and lower section. The upper
section has a large horizontal arrow and the lower section
has three small up/down arrows.
When the Twinscope is in the horizontal scanning (Sea
Scout) mode, the upper section with the horizontal arrow
will be displayed in reverse video (white arrow on black
background). When in the vertical (Probe) scanning
mode the lower section with the three small up/down
arrows will be shown in reverse video.
To change scanning modes, go to the Control Center
Menu shown at left and press the button below the left
softkey. Each time you press the button the Twinscope
will alternate between scanning modes. The display will
also change to display either the full screen vertical
(Probe) forward scan or the full screen horizontal (Sea
Scout) forward scan view.
Once the desired scanning mode has been selected, you
can press the button beneath the GO softkey (in the
center) to use either full screen view, or anyone of the
other useful views.
When in the vertical (Probe) scan mode, all the other
views on the control panel use the vertical scan. For
example, the split screen data view will show the data on
the left and a vertical forward scan on the right.
Similarly, when the Twinscope is in the horizontal (Sea
Scout) scan mode, all the other views will use the
horizontal scan. In this case, the split screen data view
will show the large digit data on the left of the screen with
a horizontal forward scan view on the right.
A navigational view of all the Twinscope's vertical scan
views are shown at right. The following section describes
each of these views in detail. The section after the next
describes each of the horizontal views in similar detail.
