BRIEF EXPLANATION OF ICON’S FUNCTION
Brief explanation of each icon.
GAIN (gain control) adjustment:
Set up the sensitivity of Radar echo.
SEA (sea-clutter rejection) adjustment:
Control the sea clutter level near the ship.
Long distant echo gain is remaining as it is, and gain is lowered as to short distance.
Adjust the target ship is clearly observe and reject the sea clutter on screen as much as
possible.
RAIN (rain-and-snow-clutter rejection) adjustment:
This type radar uses (X) band microwave (wavelength: 3cm).
This microwave can detectable more far range in fine weather, but in rain or snow weather, the
detectable range decrease remarkably.
The control is adjusted for separate the target and rain or snow as long as possible.
BRILL (brightness) adjustment: Set up the brightness of a screen.
It sets up brightly daytime and sets up not dazzle at night
MOB (Man Over board): When the crew fall into over the boat by accident.
Carry out a tap MOB icon immediately.
The radar memorizes the place latitude and longitude information, and continues displaying
the (MOB)place on a screen.
When going to rescue, navigator can take course to the(MOB)point on screen.
(Important: GPS signal must be connected in this function.)
TT DATA (target tracking)
Data which is tracking automatically is displayed.
Data is display the direction, the distance, the speed.
This function must be required the heading signal and log signal.
Measures reading of a direction can select from north(N-UP) and measure from self-ship
(H-UP).
(Heading and GPS signal is necessary.)
The speed display can select the relative speed mode or absolute speed mode.
AIS DATA (when received the AIS signal, the data of MMSI of the vessel which has
transmitted, latitude, longitude, a direction of movement, speed, rate of turn, etc. is displayed.)
(AIS receiver signal, heading and GPS signal is necessary.)
EBL (electronic bearing line)
Measure the target direction by using cursor line.
VRM (variable range marker)
Measure the target distance by using circle line.
