If the wind data is defective, the speed unit (kn, etc) is highlighted in
red.
If input error, the wind data is shown as "---" in red.
Changing wind direction readout
The wind direction readout can be changed from the direction the
wind is blowing from to the direction wind is blowing to, on the
system menu. See page 11-2. Note that the arrow indicating the wind
direction always shows the direction from which the wind is blowing.

To change the unit of wind speed from "m/s" to "knots", open the
system menu. See page 11-1.
The under-keel clearance measured by DS-30 or external echo
sounder is displayed.
In the inclined seabed, there may be a difference between the
under-keel clearance measured by DS-30 and that measured by an
echo sounder.
If the under-keel clearance data is defective the depth unit (m, etc) is
highlighted in red. If input error, the clearance data is shown as "---"
in red.
Changing unit of depth
The unit of depth can be selected among meter, feet and fathom on the
system menu. Refer to page 11-1.
The under-keel clearance measured by DS-30 or an external echo
sounder is graphically displayed. For the under-keel graphic measured
