North-up Mode [N Up]
The video is displayed so that the zenith of the PPI (0° on bearing scale) points to the due north.
Fixed targets do not flicker and are easily identified on the chart, and the true bearing of a target can
easily be read out.
Head-up Mode [H Up]
The video is displayed so that the ship’s heading line points to the zenith of the PPI (0° on bearing
scale). Since targets are displayed in their directions relative to the ship’s heading line, the operator
can view the video in the same field of view as in operating the ship at sea. This mode is suitable for
watching over other ships.
Course-up Mode [C Up]
By setting the course-up mode, own ship's course is fixed so that it is located on the zenith of the
display (0° on bearing scale). In the same way as in the North-up mode, fixed targets do not flicker,
and are stabilized even if the ship is yawing. The bearing of the heading line varies by the same shift
of own ship’s course. To change the course, press the [AZI MODE] key several times again to select
the course-up mode so as to set a new course.

move of the display. When the true motion mode is selected, the own ship’s position is set
to about 60% of the display radius in the opposite direction to its course allowing for the
influence of the current. Own ship starts moving depending upon its speed and course and
the influence of the current. Subsequently, when own ship arrives at the position of about
60% of the display radius, it is automatically reset to its initial position at about 66% of
the display radius in the opposite direction to its course allowing for the influence of the
current.

Trails Motion Mode
There are two types of trails, relative motion trails and true motion trails.
Relative motion trails : The system plots the trails of a target at a position relative to the own ship.
The operator can easily judge whether the target is approaching the own
ship.
While the own ship is moving, the system also plots the trails of land and
other fixed targets.
True motion trails
: The system plots the absolute motion trails of a target, irrespective of the
own ship’s position.
The operator can easily judge the course and speed of the target.
The system does not plot the trails of land and other fixed targets.
Trails modes provided with this system vary depending on the motion mode.
With true motion (TM) mode
: Only the true motion trails mode is available.
With relative motion (RM) mode :
The relative motion trails mode or true motion trails mode is selectable.
RM(R) is indicated while the relative motion trails mode is active.
RM(T) is indicated while the true motion trails mode is active.
While the true motion trails mode is active, this system enables the continuous use of true motion
trails even if any of the following operations is performed:
• Motion display mode change (TM / RM)
• TM reset
• Azimuth display mode change (AZI Mode)
• Center move (Off Center)
• MAP display on / off (Map)
Note: Accurate true bearing signals and speed signals are necessary for using the true motion trails
mode.

Overview of Function Operations (User Function Setting)
The following outlines the operation of each function selected from the function setting menu.
Procedures
Press the [FUNC] key for 2 seconds.
The User Function Setting menu will appear.
Specify the number for the function for which the settings are to be changed.
The following are the operation overviews of each function setting item.
[Page 1]
[1]
Mode
• Selects the function name to be indicated at the lower left of the display when the function is selected.
• When the setting is changed back to the factory setting, the initial value of the selected mode is
called.
• The following 11 modes are provided.
Coast
: Use this mode to monitor a relatively short range, for example, bays and
coasts where many boats and ships are running. (Importance is attached to
resolution.)
Deepsea
: Use this mode to monitor a relatively long range, for example, the open sea.
(Importance is attached to long-range gain.)
Fishnet
: Use this mode to detect small targets such as fishnets of round haul netters
hidden by sea clutter returns. (Importance is attached to sea clutter
suppression, and gain to moving targets lowers.)
Storm
: Use this mode when many rain / snow clutter returns or sea clutter returns
are detected in stormy weather. (Importance is attached to rain / snow
clutter and sea clutter suppression, and gain slightly lowers.)
Calm
: Use this mode when only a few rain / snow clutter returns or sea clutter
returns are detected.
Rain
: Use this mode when sea clutter is not strong but rain / snow clutter is
strong. (Importance is attached to rain / snow clutter suppression, and
gain slightly lowers.)
Bird
: Use this mode to detect flocks of sea birds.
Long
: Use this mode to monitor utmost distances in the broad ocean.
Buoy
: Use this mode to detect small targets like radio buoys in areas outside the
sea clutter area. (This mode displays targets of which detection probability
is low.)
User1
: General mode used when the nine modes above are not applicable.
User2
: General mode used when the nine modes above are not applicable.

Process (Video Process)
• Same function as Process described in Section 3.4.4.
[Page 1]
[4]
Target Enhance
• Same function as Target Enhance described in Section 3.4.3.
3-96
[Page 1]
[5]
Auto STC / FTC (Auto Sea / Rain)
• Detects unwanted waves such as rain / snow clutter and sea clutter and automatically suppresses
them.
• When the sea state or weather changes, this function automatically performs suppression processing
in accordance with the situation.
• Suppression processing is not full automatic, and requires the operator to adjust the afterimages of
unwanted waves.
• To adjust the afterimage of sea clutter, use the [SEA] dial.
• To adjust the afterimage of rain / snow clutter, use the [RAIN] dial.
• In areas where the density of unwanted waves is low, unwanted waves may remain being judged as
targets. Thus, use the automatic clutter suppression mode together with the video process mode.
• Characteristics of the automatic clutter suppression function.
Off
: Disables the automatic clutter suppression function.
Select off when rain / snow clutter and sea clutter are not strong or when the
ship is in a bay.
AUTO Sea
: Automatically detects the strength of sea clutter, and performs the most
suitable sea clutter suppression processing.
Even when the strength of sea clutter varies depending on the wind direction,
AUTO Sea performs the most suitable suppression processing.
Land like islands can be displayed naturally.
Since rain clouds outside sea clutter areas are recognized as land, there is no
effect of suppressing rain / snow clutter.
AUTO Sea/Rain : Along with AUTO Sea, AUTO Rain automatically detects the strength of
rain / snow clutter, and performs the most suitable rain / snow clutter
suppression processing.
When rain clouds are scattered about, AUTO Rain performs rain / snow
clutter suppression processing for only the rain-cloud areas.
Since land is recognized as rain clouds, land videos become obscure.

yy
Gain Offset
• Corrects gain while the function mode is called.
• Since the displayed noise level varies depending on the combination of the video process mode and
the interference rejection level, gain needs fine adjustment for always obtaining the highest level.
• The gain correction function saves the correction value set by the gain adjust in each function mode,
so it can obtain the highest gain without the gain adjust being operated when the function mode is
changed.
• To set high gain, set a value on the “+” side.
• To set low gain, set a value on the “-” side.
• When the radar interference rejection level is increased, the noise level is lowered. Thus, set a gain
correction value to the “+” side.
• When the video process mode 3Scan CORREL , 4Scan CORREL , or 5Scan CORREL is
used, the noise level is lowered. Thus, set a gain correction value to the “+” side.
• When the video process mode Remain or Peak Hold is used, noise is hard to disappear. Thus,
set a gain correction value to the “-” side.
[Page 5]
[2]
PRF
• Same function as in the Pulse Repetition Frequency described in 3.8.3.
[Page 5]
[3]
Small Buoy Detection
• When the automatic sea clutter suppression function is used, this mode is used to process signals for
detecting small targets.
Off : Activates the general signal processing mode.
On : The signal processing mode for detecting small targets.
[Page 5]
[4]
Fishnet Detection
• Use this mode to detect small targets hidden by sea clutter returns.
• The simultaneous use with the automatic rain / snow clutter suppression function will increase effects.
Off : Activates the general signal processing mode.
On : Activates the fishnet detection mode.
[Page 5]

Antenna Height
• Set the height of radar antenna above sea level.
• The STC/FTC curve is changed.

4.1.7 Using MOB [MOB]
The marker (anchor symbol) function displays a dotted line from the marker input position to the own
ship's position, and indicates the range, bearing, and required time from the own ship's position to the
marker. (The navigator needs to be connected.)
For example, the function can be used for following purposes:
To confirm the drifting distance from where the ship was anchored.
To record a position of man overboard.
Procedures
Press the [MOB] key.
A marker will be displayed at the own ship's position on the radar display at the moment
when the [MOB] key is pressed. The own ship and the marker are connected with a dotted
line.
