Adjusting Gain on the Radar Screen Manually

For optimal radar performance, you can manually adjust the gain.

NOTE: Depending upon the radar in use, the gain setting configured for use in one radar mode may or may not be applied to other radar modes or to the Radar overlay.
  1. From a Radar screen or the Radar overlay, select Menu > Gain.
  2. Select Up to raise the gain, until light speckles appear across the Radar screen.

    Data on the Radar screen is refreshed every few seconds. As a result, the effects of manually adjusting the gain may not appear instantly. Adjust the gain slowly.

  3. Select Down to lower the gain until the speckles disappear.
  4. If boats, land, or other targets are within range, select Down to lower the gain until the targets begin to blink.
  5. Select Up to raise the gain until the boats, land, or other targets appear steadily lit on the Radar screen.
  6. Minimize the appearance of nearby large objects, if necessary.
  7. Minimize the appearance of side-lobe echoes, if necessary.
