SHIFT MODE: Own ship position, or sweep
origin, can be displaced manually or
automatically. For automatic displacement,
the amount of shift is calculated with ship
speed, and the amount is limited to 60% of
the range in use. For example, if the "Auto
Shift Speed" setting is 15 knots and the ship
is running at 10 knots, the amount of shift will
be about 40%. The formula for determining
shift amount is as below. Requires speed
data.
Ship's speed
X 0.6 = Amount of shift(%)
Shift speed setting
AUTO SHIFT SPEED: Sets the automatic
shift maximum speed. The setting range is
0-99.
NAV DATA: Chooses the amount of nav data
to display among two, three and four items.
Requires appropriate sensors.

TX SECTOR BLANK: In some installations it
may be unavoidable to locate the antenna
where an object (mast, etc.) will prevent
transmission within its breadth. You should
disable transmission within this area by
turning on this feature and setting the area
with BLANK START and BLANK AREA below.
BLANK START: Sets the starting point of the
TX sector blanking area.
BLANK AREA: Sets the end point of the TX
sector blanking area.
RANGE UNIT: Chooses the unit of range
measurement among nautical miles,
kilometers and statute miles.
DEPTH UNIT: Chooses the unit of depth
measurement among meters, feet, fathoms
and Passi/Braza. Requires depth data.
SPEED UNIT: Chooses the unit of speed
measurement among knot, mile per hour and
kilometer per hour. Requires speed data.
TEMP UNIT: Chooses the unit of water
temperature measurement from Celsius and
Fahrenheit. Requires water temperature data.
WIND UNIT: Chooses the unit of wind
measurement among mile per hour, kilometer
per hour and meters per second. Requires
wind data.
WIND DIRECTION: Choose the wind
direction reference from true and apparent.
True is the speed and direction (in relation to
ship's bow) of the wind felt or measured when
stationary. Apparent is the direction (in
relation to ship's bow) and speed of the wind
as it appears to those on board, relative to
the speed and direction of the boat;
combination of the true wind and the wind
caused by the boat's movement. Requires
wind data.

RANGE: Chooses the ranges to use.
Minimum of two ranges must be turned on.
When the range unit is km, "0.125" replaces
"0.125" and "24" newly appears.
