[. . . ] Typically, the best sensitivity level shows a good solid bottom signal with Colorline and some surface clutter. When the unit is in the automatic mode, sensitivity is automatically adjusted to keep a solid bottom signal displayed, plus a little more power. Situations occur when an increase or decrease in sensitivity is needed. An increase in sensitivity is necessary when you want to see more detail. A decrease in sensitivity will clear up the screen when it becomes cluttered by tiny air bubbles caused by boat wakes or wave action. The control bar used to adjust sensitivity up or down is the same whether the unit is in the automatic or manual mode. In automatic you can adjust sensitivity up to 100 percent, but the unit will limit your minimum setting. In auto, the unit will continue to make small adjustments, allowing for the setting you selected. In manual mode, you have complete control over sensitivity with the ability to set it anywhere from zero to 100 percent. Once you select a level in manual, the unit will continue to use that exact sensitivity setting until you change it or revert to auto mode. When it is set at the desired level, press EXIT. 71 Sonar Menu with Sensitivity command selected (left). The Sensitivity Control Bar (right). To adjust sensitivity in manual mode: 1. First, turn off Auto Sensitivity: from the Sonar Page, press MENU| to AUTO SENSITIVITY|ENT. To turn Auto Sensitivity back on: From the Sonar Page, press MENU| to AUTO SENSITIVITY|ENT|EXIT. Tip: For quicker sensitivity adjustments, leave the Sensitivity Control Bar on the screen as the chart scrolls. You can see the changes on the screen as you press the up and down arrows. This is handy when there is a lot of clutter in the water and you are matching the sensitivity to rapidly changing water conditions. Sonar Chart Mode The default color scheme for the sonar chart is White Background, but we offer other variations to suit your viewing preferences. You can select the chart to be displayed in Grayscale, Reverse Grayscale, Blue Background, Nightview, IceView or Bottom Color Tracking. 72 Sonar Page & Sonar Chart Display Options The Sonar Page Menu offers four chart display options. To access them, press PAGES| to SONAR| to Option Name|EXIT. Pages Menu, showing sonar chart display options. Full Sonar Chart This is the default mode used when the unit is turned on for the first time or when it is reset to the factory defaults. Depth scales on the right side of the screen aid in determining the depth of targets. The bottom depth and surface temperature (if equipped with a temperature sensor or a transducer with a temp sensor built in) show at the top left corner of the screen. This changes all echoes into short horizontal bars, replicating a flasher sonar.
