The radar transmits until you change the radar mode to Standby or Off.
¾ Set 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.
¾ To correct:
• position the vessel about 50 yards to 100 yards (45 m to 90 m) from a straight-walled jetty or
similar feature that produces a straight line echo on the display.
• 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.
¾ To 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.
¾ Select OK to confirm the new setting.
