Section 1 Introduction
1.1 Read Before Use
About the Quick Operation Guide
For more details, please read the Operation Manual.
Please keep this Quick Operation Guide in an easily accessible place.
About the Radar
Use the radar solely as a navigation aid. Also, the final decision of manoeuvring must be made by the
person who manoeuvres the ship. If the final decision on manoeuvring is solely made based on the
information displayed by the radar, it may cause accidents such as collision and running aground.
About sea clutter suppression
Do not adjust the sea clutter suppression function until all sea clutters are erased in the close distance
range.
Otherwise, targets such as vessels and dangerous objects will be suppressed in addition to echoes
from waves, causing to interfere detection.
When using the sea clutter suppression function, always perform optimum suppression adjustment.
About rain/snow clutter suppression
Do not adjust the rain/snow suppression function excessively. Otherwise, targets such as vessels and
dangerous objects will be suppressed in addition to echoes from rain and snow, causing to interfere
detection.
When using the rain/snow clutter suppression function, always perform optimum suppression
adjustment.
About the target tracking function
Use the target tracking function solely as a navigation aid. Also, the final decision of manoeuvring must
be made by the person who manoeuvres the ship. If the final decision on manoeuvring is solely made
based on the information acquired from the target tracking function, it may cause accidents.
Vectors, target numeric data, alarms and other information displayed by the target tracking function
may contain errors. Note that targets which cannot be detected by the radar can neither be acquired
nor tracked.
If the final decision on manoeuvring is solely made based on the information displayed by the radar, it
may cause accidents such as collision and running aground.

assignment function, the [Display Brightness] dialogue is displayed.
It is possible to adjust the brightness of the display section by rotating the [MULTI] dial.
Memo
When "DISP Brightness" is not being displayed in the Key Assignment Indication Area, press the
[MULTI] dial for a long time.The Display Brightness function will be assigned to the [MULTI] dial.

Section 2 Basic Operation 2-4
2.4 Changing the Observation Range
1 Click on the [Range Scale] button in Range and mode information and select a range
from the context menu.
[Points on adjustments]
Increasing the observation range will enable a wider range to be observed.
However, a video image is small and the ability to detect targets near own ship decreases.
Therefore, when observing the vicinity of own ship, use the smaller observation range.
Decreasing the observation range will enable the vicinity of own ship to be enlarged. However,
caution must be taken because video images of the area beyond the observation range cannot
be displayed.

2.5 Adjusting Gain
1 Drag the [Gain] (reception gain adjustment) slider dial in Radar signal information,
turn the trackball, and set up reception gain.
Moving the slider to the right increases gain.
Moving the slider to the left decreases gain.
The current reception gain level is indicated by the bar and a numeric value.
[Points on adjustments]
As reception gain is increased, the range in which radar images can be observed widens; however, if
gain is increased too high, receiver noise, false echoes and other undesired signals will increase on
the screen, lowering the visibility of targets.
Also, it gets easier to see the screen display if gain is decreased to observe cluttered targets and close
range, but be careful not to overlook small targets.

2.6 Removing Sea Clutters
1 Drag the [Sea] (sea clutter adjustment) slider dial in Radar signal information, turn the
trackball, and adjust the amount of images by sea clutter displayed on the screen so
as to make display easy to observe.
Moving the slider to the right decreases the amount of images by sea clutter.
Moving the slider to the left increases the amount of images by sea clutter.
The current level of sea clutter suppression is indicated by the bar and a numeric value.
[Points on adjustments]
The sea clutter suppression function decreases the amount of images by sea clutter by lowering
reception gain at close range. When reception gain is lowered, the effectiveness of sea clutter
suppression increases; however, if excessive effect is applied, please note that targets having weak
signal strength such as buoys and small ships will disappear.
Using the function of automatic sea clutter suppression mode
The sea clutter suppression in accordance with the intensity of sea clutter is possible. Use this mode
when the sea clutter's intensity differs according to directional orientation.
1 Click on the Automatic Sea Clutter Suppression button.
[AUTO] (automatic) is displayed on the automatic sea clutter suppression button.
Each time this button is clicked on, the display switches between [AUTO] (automatic) and
[MAN] (manual).
2 Drag the sea clutter adjustment slider dial, turn the trackball, and adjust the amount of
images by sea clutter displayed on the screen.
Even while automatic sea clutter is being suppressed, the amount of images can be
fine-adjusted manually.

2.7 Removing Rain/Snow Clutters
1 Drag the [Rain] rain/snow clutter adjustment slider dial in Radar signal information,
turn the trackball, and adjust the amount of images by rain/snow clutter displayed on
the screen so as to make display easy to observe.
Moving the slider to the right decreases the amount of images by rain/snow clutter.
Moving the slider to the left increases the amount of images by rain/snow clutter.
The current level of rain/snow clutter suppression is indicated by the bar and a numeric value.
[Points on adjustments]
When the amount of images by rain/snow clutter is decreased, the outlines of targets hidden by images
of rain/snow will appear, but please note that small targets may be missed. Since this can also reduce
sea clutter, it is effective to use it together with the sea clutter rejection function.
Normally, set the level of rain/snow clutter suppression to 0.

Description
Display image
[N UP] North UP (North Up)
• The video is displayed so that the zenith of the PPI 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.
[H UP] Head UP (Head Up)
• The video is displayed so that the ship’s heading line is
displayed at the top of the screen. 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. Therefore, This mode is suitable for
watching over other ships
• This is not available for TM (True Motion) mode.
[C UP] Course UP (Course Up)
• At the setting of Course Up, the ship’s heading (HDG) is fixed
and displayed immediately above the screen. Similar to true
bearing display, the positions of stationary targets will
not deviate even if yawing occurs in the ship: targets
are displayed stably and the bearing of the heading line
moves only according to the amount of change in own
ship's course. To change the course, select the Course
UP display by clicking on the Azimuth mode combo box
several times. A course can be set again.
