Adjusting Sensitivity and Colorline Select the Sensitivity or Colorline menu options in the Sonar menu and adjust them by dragging the bar vertically or by using the Cursor keys. Ú Note: Minor adjustments can be made by tapping above or below the slider bar or pressing the Cursor keys. Ú Note: When the Sensitivity or Colorline slider bar is displayed, it is automatically selected and adjustments can be made up/down with the Cursor keys. Stop sonar Select the Stop sonar menu option to stop the sonar from pinging. Use the stop sonar option anytime you want to disable the sonar but not power off the unit. Advanced Sonar options The Advanced option is only available when cursor is not active. Noise rejection Signal interference from bilge pumps, engine vibration and air bubbles can clutter the image. The noise rejection option filters the signal interference and reduces the on-screen clutter. Surface clarity Wave action, boat wakes, and temperature inversion can cause onscreen clutter near the surface. The surface clarity option reduces surface clutter by decreasing the sensitivity of the receiver near the surface. Scroll speed You can select the scrolling speed of the Sonar image on the screen. A high scroll speed updates the image fast, while a low scroll speed presents a longer history. Ú Note: In certain conditions it may be necessary to adjust the scroll speed to get a more useful image. Such as Sonar | HDS Gen3 Operator Manual 67
