Adjust Trigger Delay
This feature eliminates the time lag between real radar returns and the time it takes data to be
processed by the radar software, a common issue with all radars.
Caution: If you have any doubt about your understanding of the Trigger Delay feature, you
should have it set up by a qualified radar technician.
•
The radar should already be in STANDBY mode, so press PWR for 2 seconds to switch the
radar into transmission mode. A confirmation message will appear, press

to select
Yes
.
• Press Menu , select
Gain
and press Ent . Press to increase the Gain level to around
15%. One or two red rings with blue borders should be visible on the screen, depending
on the wattage of your radar antenna.
•
Press | to Adjust Trigger Delay , then press Ent .
• The 2 kW model, the LRA-1800, will have only one ring on the display.
•
The 4 kW model, the LRA-2400, will have two rings on the display. See the following
figures.
Before adjusting the Trigger Delay for 4 kW radars, two rings will be shown on the screen (left). As
Trigger Delay is increased, the larger ring will start to get smaller. The small ring will disappear (right).
You may have to increase gain in the previous step if the rings are not visible. Increase gain
until you have solid red rings shown on the screen, like in the preceding example. Increasing
Gain too much can cause the rings to be distorted.
• 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.
