Item Description
2 DEPTH Chooses unit of depth measurement, or turn
depth indication off.
3 DEPTH GRAPH SCALE Chooses depth scale range. The echogram
shows the last 30 minutes of sounding along
the ship’s track.
4 DEPTH MARK Chooses 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 Chooses unit of wind speed measurement, or
turn wind indication off.
7 TEMP Turns water temperature indication on/off.
8 DATE-TIME Chooses how to display date and time: OFF,
UTC or LOCAL.
9 LOCAL TIME ADJ If LOCAL is selected at 8 DATE-TIME, roll the
wheel to set the time difference between local
time and UTC time. A negative value may be
chosen by spinning the wheel past zero.
0 WPT DATA Turn waypoint data off, or display range and
bearing to waypoint.
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 the direction to which
the current is flowing away own ship position, relative to north.
