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.

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, then select GAIN and press ENT, which will call up the Gain vertical control bar. 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.

•Now from the Radar Setup menu, press →↓ to ADJUST TRIGGER DELAY, then press ENT. The Adjust Trigger Delay vertical scrollbar will appear.

The 2 kW models, the LRA-1000 and LRA-1500, will have only one ring on the display. The 4 kW radars — LRA-2000, LRA-4000 and LRA-5000 — 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 distortion of the rings.

•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.
