bearing alignment setting, so that the heading marker and land mass intersect.

Adjust antenna height

Set the radar scanner height relative to the water surface. The Radar uses this value to

calculate the correct STC settings.

Adjust local interference reject

Interference from some onboard sources can interfere with the Broadband radar. One

symptom of this could be a large target on the screen that remains in the same relative

bearing even if the vessel changes direction. Choose from Local interference rejection LOW,

MED or HIGH. Default is LOW

Sidelobe suppression

Occasionally false target returns can occur adjacent to strong target returns such as large

ships or container ports. This occurs because not all of the transmitted radar energy can be

focused into a single beam by the radar antenna, a small amount energy is transmitted in

other directions. This energy is referred to as sidelobe energy and occurs in all radar systems.

The returns caused by sidelobes tend to appear as arcs.

 Note: This control should only be adjusted by experienced radar users. Target loss in harbour

environments may occur if this control is not adjusted correctly.

When the radar is mounted where there are metallic objects near the radar, sidelobe energy

increases because the beam focus is degraded. The increased sidelobe returns can be

eliminated using the Sidelobe Suppression control in the Radar installation menu.

By default this control is set to Auto and normally should not need to be adjusted. However

if there is signi cant metallic clutter around the radar, sidelobe suppression may need to be

increased. The control should be adjusted as follows:

• Set Radar range to between 1/2 nm to 1 nm and Sidelobe Suppression to Auto.

• Take the vessel to a location where sidelobe returns are likely to be seen. Typically this would

be near a large ship, container port, or metal bridge

• Traverse the area until the strongest sidelobe returns are seen.

• Change Auto sidelobe suppression to OFF then select and adjust the sidelobe suppression

control until the sidelobe returns are just eliminated. You may need to monitor 5-10 radar

sweeps to be sure they have been eliminated.

• Traverse the area again and readjust if sidelobes returns still occur.

• Exit the installation menu.

Restore radar to Factory Default

This can be used to revert all user adjustments.

Video In con guration

Press the menu key when on the video page or panel to open the setup

dialogue.

Enable PAL or NTSC depending on the video ouput standard of the

selected camera.

You can optimize the video display by adjusting the video image

settings (brightness, saturation, etc.). The settings are applied individually

for each video source.

Mirror image may be applied where the camera is providing a rear view,

and the user wishes to see objects as they would appear in a vehicle

rearview mirror, ie, on the same side as they actually are.
