Item Description
2 DEPTH Selects unit of depth measurement, or turn depth indication off.
3 DEPTH
GRAPH SCALE
Selects depth scale range. The echogram shows the last 30 minutes of
sounding along the ship’s track.
4 DEPTH MARK Selects the depth at which to show the depth mark.
5 CURRENT Turns ocean current display on (ocean current relative to North) or off.
6 WIND Selects unit of wind speed measurement/wind speed format. Wind vector
format can be selected from three choices:
RELATIVE: Apparent wind measured by wind meter, with ship's bow as
reference.
TRUE THEORETICAL: Apparent wind minus ship's movement, with ship's
bow as reference.
TRUE NORTH: Apparent wind minus ship's movement, with North as
reference.
7 TEMP Turns water temperature indication on/off.
8 DATE-TIME Selects how to display date and time: OFF, UTC or LOCAL.
9 LOCAL TIME
ADJ
If LOCAL is selected at 8 DATE-TIME, roll the scrollwheel to set the time
difference between local time and UTC time. A negative value may be
selected by spinning the scrollwheel past zero.
0 WPT DATA Turn waypoint data off or select waypoint data reference, true or relative.
4. Push the right button twice to close the menu.
Note: Wind and current data require appropriate sensors. Depth data requires
appropriate echo-sounding equipment. Wind vector shows a direction from
which the wind blows in, relative to own ship heading, and labeled "T *." Wind
velocity is a true wind speed as a result of compensating for own ship’s speed
and orientation. Ocean current (tide) is shown relative to bow in head-up, cursor
gyro and course-up, and reference to North in north-up and true motion.
