4. Press ↑ to increase the level of Trigger Delay, which will decrease the
size of the ring. If you have a 4 kW radar, as the large ring decreases in
size, the smaller ring in the center of the screen will disappear, leaving
only one ring.
Increase Trigger Delay to diminish the size of the red ring (left). To set
Trigger Delay correctly, reduce the ring to as small a size as possible,
while keeping a black circle in the middle (enlarged view, right).
In either case, continue to increase the Trigger Delay level until the
ring is as small as possible, while keeping a black circle in the middle.
Every radar is different, but typically, a setting between 35 and 42 per-
cent will get the job done.
If you over apply the Trigger Delay, the black circle will disappear. De-
crease the Trigger Delay level and it will reappear.

Adjust Heading Line
The Heading Line command is used to make sure the green heading
line (zero point) on your display is lined up with the bow of your vessel.
(Before heading line adjustment) (After heading line adjustment)
The bow of the ship is lined up with the tip of the peninsula (left), but the
green heading line is not. Adjusting the heading line will allow you to align
the direction of the heading line with the direction of the bow (right).
