[. . . ] (When you reach the maximum or minimum limit, a tone sounds. ) At left, Sonar Menu with Sensitivity command selected. At right, the Sensitivity Control Bar. 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. NOTE: To return to the original factory setting for Auto Sensitivity, see the entry in this section on Reset Options. If sensitivity is in manual mode, the Reset Options command will switch back to Auto and reset the factory setting at the same time. 57 Tip: For quicker sensitivity adjustments, try leaving the Sensitivity Control Bar on the screen as the chart scrolls. You can see the changes on the screen as you press the up or down arrows. This is handy when there's a lot of clutter in the water, and you are matching the sensitivity to rapidly changing water conditions. Set Keel Offset This unit measures water depth from the face of the transducer. Since the transducer is installed below the water surface, the distance displayed by the digital depth, chart depth scale, chart cursor or fish symbols is not the exact water depth. If the transducer is 1 foot below the surface, and the screen shows the water depth as 30 feet, then the actual depth is 31 feet. On sailboats or other large vessels with deep drafts, the distance between the transducer installation and the keel or lower engine unit can be several feet. In those cases, an inexact depth reading could result in grounding or striking underwater structure. The Keel Offset feature eliminates the need for the navigator to mentally calculate how much water is under his keel. Keel Offset lets you calibrate the digital depth indicators: chart depth scale, chart cursor depth and fish symbol depth displayed on the screen. To calibrate the depth indicators, first measure the distance from the face of the transducer to the lowest part of the boat. We enter this as a negative 3. 5 feet, which makes the depth indicators perform as if the transducer's lower in the water than it really is. Press to so that the displayed number shows a minus (­) sign instead of the plus (+) sign. The depth indicators now accurately show the depth of water beneath the keel. NOTE: If knowing the exact depth of water beneath the keel is less important, you can calibrate the depth indicators so that they show the actual water depth from surface to bottom. To do this, first measure the distance from the face of the transducer up to the surface (the water line on the boat). This will be entered as a positive 1. 5 feet, which makes the depth indicators perform as if the transducer's higher in the water than it really is.
