3.3 Adjustments

Do the following in order to adjust the radar.

1) Adjustment of picture

1.Press the [POWER] key on the display unit. The display should light. In approximately one minute, ST-BY appears at the screen center.

2.When ST-BY appears press the [TX] key. The radar will start transmitting, and you will probably see some targets, even though the radar is not yet properly adjusted.

3.Adjust the GAIN to display a small amount of noise on the screen.

4.Press the [–] key several times to select the minimum range. Adjust the STC to display nearby radar targets clearly on the screen. Too much STC action will eliminate small targets, and too little STC action will cause the screen to be so full of targets and noise that it is hard to determine which target is which as compared to visual sightings.
