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 percent will get the job done.
If you over apply the Trigger Delay, the black circle will disappear. Decrease the Trigger Delay
level and it will reappear.
