¾Set Radar Range offset (trigger Delay)
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. (The radar range offset is also known as the trigger delay.)
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”. To rectify this adjust the radar range offset.
¾To correct:
•position the vessel about 50 yards to 100 yards (45 m to 90 m) from a
•Select the 1/8 mile range
•Adjust the gain setting until a reasonably good image of the jetty echo is displayed.
•Adjust the radar range offset to make the jetty echo appear as a straight line on the display, as shown:
•
If it‘s not possible to position the vessel near a suitable target, perform a rough set up of the range offset by using the circle at the center of the radar screen as a guide.
If your Radar screen has:
•a wide black circle around the center, decrease the radar range offset until it almost disappears.
•no black circle at the center, increase the radar range offset until a black circle just starts to appear at the center.
¾To change the radar range offset:
•Display the Radar screen and main menu. If you can't see the Adjust Radar button, select Return.
•Select Adjust Radar, then select Installation.
•Select Radar Range Offset then use Up and Down to adjust the current setting.
