You can choose any segment of the water, as long as the distance between the upper limit and lower limit is 10 feet (10 meters) or more. To change the upper limit, first make certain the unit is in the manual mode. Next, press a menu key until the "UPPER LIMIT" menu appears. Now press the down arrow key to increase the upper limit or the up arrow key to decrease it. After you've finished, wait a few seconds and the menu will scroll off the screen's left side. Pressing the PWR key also clears it. 21 FOOT UPPER LIMIT To change the lower limit, again make certain the unit is in the manual mode. Now press the down arrow key to increase the lower limit or the up arrow key to decrease it. When you have the limit set, wait a few seconds and the menu will scroll off the screen's left side. Pressing the PWR/CLEAR key also clears it. 20 SENSITIVITY The sensitivity menu lets you control the unit's ability to pick up echoes. A low sensitivity level excludes much of the bottom information, fish signals, and other detail. High sensitivity settings lets you see features, but it can also clutter the screen with noise and other unwanted signals. Typically, the best sensitivity level shows a good, solid bottom signal with grayline. This sonar unit adjusts the sensitivity level to keep a solid bottom signal on the screen. However, situations occur where it becomes necessary to increase or decrease the sensitivity level. Typically, this occurs when you wish to see more detail, so you need to increase the sensitivity. The procedure to adjust it is the same whether the unit is in the automatic or manual mode. To change the sensitivity level, first press the menu key until the sensitivity menu appears. If the unit is in automatic, the menu shows "AUTO SENS. " Otherwise, the menu shows "MAN SENS. " Now press the up arrow key to increase the sensitivity, the down arrow to decrease it. Echoes scrolling onto the screen will also show the effects of the sensitivity change. If you reach the maximum or minimum sensitivity level, a tone sounds alerting you to the limits. After you've adjusted the unit to the desired sensitivity level, press the PWR key to clear the display.
