5.4.27 Change to ALL PPI screen ( ALL PPI )
Press the "ALL PPI" key and all data elements and soft keys
will disappear from the screen, displaying a full-frame radar
image. The range, ring interval and display mode are shown
in the upper left corner. The only controls that have any
effect in this mode are the "RANGE UP", "RANGE DOWN",
"MENU" and POWER buttons, along with the cursor pad.
Pressing any other keys will exit ALL PPI and return the
display to the normal PPI screen mode.
5.4.28 Change to ALL PPI/PPI screen ( ALL PPI2 )
When you press the "ALL PPI2" key, all data elements and
soft keys will disappear from the screen, and two identical
PPI windows will appear side-by-side. The range, rings
interval, display mode are displayed on the upper left of each
window. The only controls that have any effect in this mode
are the "RANGE UP", "RANGE DOWN", "MENU" and
POWER buttons, along with the cursor pad. Pressing any
other keys will exit ALL PPI2 and return the display to the
normal PPI/PPI screen mode. The radar pictures are
refreshed with separate, alternating scanning intervals for
each screen. The right screen picture is frozen during the
refresh period for the left screen, and vice versa. We
recommend when cruising at higher speeds to use a single
PPI screen for continuous image refreshing.
