The scanner alerts only once for each range when it meets both of the following two conditions.
First condition is heading for Alert Point. This is cleared when you heading is within ±45˚ of the
value that is set in Set Heading.
The second condition is speed. It meets this condition when the current speed exceeds the speed
that is set in Set Speed Limit.
For example, see the following illustration. Car 1 is traveling within the range of the alert location point
and its heading is within the point’s set direction.
Car 2 is traveling within the range of the alert location, but its direction is outside the point’s set direction.
If Car 1 is running at a speed higher than the limit set for the point, the scanner rings an Alert, the display
changes to Location Alert Mode and the Alert Light is turned on.
If Car 1 is running at speed lower than the limit set for the point, the scanner does not ring an alert, the
display changes to Location Alert Mode.
If Car 1 accelerates to a speed higher than the limit set for the point after it enters range, the scanner will
ring an Alert and the Alert Light is turned on.
On the other hand, no Alert (Alert display, Alert Light, and Alert Beep) will sound for Car 2 regardless of its
speed.
Lockout Operation
The scanner temporarily locks out the current Location Alert if you press [L/O] once while an alert for the
location is active. The scanner automatically unlocks the locked out location when it moves 4 miles or
more from the Alert Point.
The scanner permanently locks out the current Location Alert if you press [L/O] twice in a second. As long
as you do not unlock the locked out location at menu (See: Set Lockout), Location Alert Operation and
Alert Light for the locked out location does not work.
Turn [Scroll Control] during a location alert to temporarily lockout the displayed Location Alert.
