1. OPERATION

PANEL DIMMER:
You may adjust panel
backlighting from among OFF, LOW,
MEDIUM and HIGH.
HUE:
The default hue setting (DAY) display is
most suitable for daytime viewing. For
nighttime viewing you may reverse this
arrangement (NIGHT).
TRIPLOG RESET:
You may reset distance
run to zero by choosing YES. Navigator or
speed log is required to display distance run.

EBL REFERENCE: The EBL readout may be
chosen from relative (relative to own ship’s
heading) or true (referenced to the North).
Heading data required for true bearing.
Note:
If no bearing data is input, course data
from the GPS navigator is used. In this case
ship’s speed must be more than two knots.
BEARING READOUT:
Course indication may
be shown in true or magnetic (magnetic
compass) degrees. Heading data required for
true degrees.
CURSOR POSITION:
Chooses the
information to show for the cursor position:
latitude and longitude or range and bearing
from own ship. Latitude and longitude
position requires a navigator.
TRIP SOURCE:
Chooses the criteria for
calculating distance run: latitude and
longitude or speed. Requires navigator or
speed log.
WIND SPD/DIR:
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.
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
Shift speed setting
X 0.6 = Amount of shift(%)
AUTO SHIFT SPEED:
Sets the automatic
shift maximum speed. The setting range is
1-99.
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 BLANKING START and BLANKING
AREA below.
BLANKING START:
Sets the starting point
(000-359°) of the TX sector blanking area.
BLANKING AREA:
Sets the end point of the
TX sector blanking area (000-135°).
LOCAL TIME SETUP:
Enter time difference
between local time and UTC time to use local
time. Press ▲ or ▼ to set value.
ANTENNA SPEED:
Chooses antenna
rotation speed from 24 rpm and AUTO. Use
AUTO to automatically change the antenna
rotation speed (24-41 rpm) according to pulse
length*. Choose “24 rpm” to rotate the
antenna at 24 rpm regardless of pulse length.
* = Short pulse at high rotation speed; long
pulse at slow rotation speed.

RANGE: Chooses the ranges to use.
