Siren enable
The Siren enabled option must be set in order for the unit to activate the buzzer when an
alarm condition arises.
Its setting also determines the operation of the external alarm output.
Radar installation
The radar system requires radar sensor specific settings in order to adjust for a number of
variables found in different installations.
Ú
Note: The installation settings available depends on the radar type and model.
Radar source
In a system with more than one radar sensor, the device to configure is selected from this
menu.
Ú
Note: Radars that support dual radar mode are represented twice in the source list, with
an A and B suffix.
Radar status
Displays scanner information and scanner features, primarily used for information and to
assist with fault finding.
Adjust antenna height
Set the radar scanner height relative to the water surface. The Radar uses this value to
calculate the correct STC settings.
Select antenna length
Select the proper antenna length.
Adjust range offset
The radar sweep should commence at your vessel (a radar range of zero). You may need to
adjust the radar range offset to achieve this. If this is set incorrectly, a large dark circle in the
center of the sweep might occur. You might notice straight objects such as straight sea walls
or piers having curves or an indentation. Objects close to your vessel may appear pulled in or
pushed out.
Adjust the range offset as below when the vessel is about 45 to 90 m (50 to 100 yards) from a
straight-walled jetty or similar feature that produces a straight line echo on the display.
1 Position the vessel in relation to the jetty.
2 Adjust the range offset to make the jetty echo appear as a straight line on the
display.
