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.

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.

Range Scale button

[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.

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.

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.

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.

[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.

The current level of rain/snow clutter suppression is indicated by the bar and a numeric value.
