Gain has a manual and an automatic mode. You toggle between automatic and manual
mode in the slide bar, or by pressing and holding the rotary knob.
Sea clutter
Sea clutter is used to filter the effect of random echo returns from waves or rough water near
the vessel.
When you increase Sea clutter, filtering the on-screen clutter caused by the echoes of waves
is reduced.
The system includes predefined Sea clutter settings for harbor and offshore conditions for all
radar systems except Halo, in addition to the manual mode where you can adjust the
settings. For all radar systems except Halo, you select Sea clutter modes from the menu, or by
a long press on the rotary knob. You can only adjust the Sea clutter value in manual mode.
Auto Sea Offset
To allow fine tuning of the Sea control while in Auto mode (Auto uses directional adaptive
clutter rejection), the Auto setting may be offset.
Rain clutter
Rain clutter is used to reduce the effect of rain, snow or other weather conditions on the
radar image.
The value should not be increased too much as this may filter out real targets.
Using the cursor on a radar panel
By default, the cursor is not shown on a radar panel.
When you position the cursor on the radar panel, the cursor position window is activated.
Go to cursor
You can navigate to a selected position on the image by positioning the cursor on the panel,
and then using the go to cursor menu option.
The cursor assist function
Ú
Note:
The cursor assist function is available if it is enabled. Refer to "Customizing the long press
feature" on page 18.
The cursor assist function allows for fine tuning and precision placement of the cursor
without covering details with your finger.
Activate the cursor on the panel, then press and hold your finger on the screen to switch the
cursor symbol to a selection circle, appearing above your finger.
Without removing your finger from the screen, drag the selection circle to the desired
position.
When you remove your finger from the screen the cursor reverts to normal cursor operation.
Advanced radar options
Menu options can vary depending on your radar's capability.
Noise Rejection
Sets the amount of noise filtering applied by the radar. Target sensitivity is increased at
longer ranges when this control is set to Low or High, but does cause some loss of target
discrimination.
Ú
Note:
To get maximum range performance from the radar, transmit on one range only,
set the Noise Reject control to High and the threshold as low as possible. The default is
30% for less clutter on the screen. In some areas where extreme high interference may
exist, try OFF for best radar image.
