Simrad NSO evo3S MPU - Using the Cursor on a Radar Panel

In addition, CALM, MODERATE or ROUGH STC Curve settings are available in the Radar
options menu to better optimize the radar image to your liking.
Gain
The gain controls the sensitivity of the radar receiver.
A higher gain makes the radar more sensitive to radar returns, allowing it to display weaker
targets. If the gain is set too high, the image might be cluttered with background noise.
Gain has a manual and an automatic mode. You toggle between automatic and manual
mode in the slide bar.
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, in
addition to the manual mode where you can adjust the settings. You select Sea clutter
modes from the menu. You can only adjust the Sea clutter value in manual mode.
Auto Sea Offset
(Halo Radar only)
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 17.
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.
