[. . . ] In the example screen shown below, the bottom depth has descended to a point where you can change the range to 150 feet. To do this, simply press the right arrow key while the Auto Range menu is displayed. When you're finished with this menu, press the EXIT key to erase it. RANGE - Manual You have complete control over the range when the sonar is in the manual mode. To change the range, first make certain the unit is in the manual mode. Next, press the MENU key and the up or down arrow keys until the range menu appears as shown at right. Press the left or right arrow keys to decrease or increase the range. The available ranges are 0-5, 10, 20, 30, 40, 60, 100, 150, 200, 300, 500, 800, and 1000 feet. After the desired range is displayed, press the EXIT key to erase the range menu. NOTE: The depth capability depends on the frequency selection, transducer installation, water and bottom conditions, and other factors. UPPER AND LOWER LIMITS You can enter any range when the unit is in the manual mode. The unit lets you enter any upper and lower limit, provided there is at least five feet separating them, for example, from 20 to 25 feet. (On the screen below left, the upper limit is 0 and the lower limit is 60. ) Using the upper and lower limit range option, we changed the range from 0 to 60 feet to 24 to 54 feet. This "zoomed" the display to a 30 foot range. As you can see, the fish arches near the bottom are much larger and easier to see. In fact, a possible fish on the bottom shows on the enlarged screen that is not even visible on the left!Not only does this make it easier to see targets, but you can more accurately determine their depth, due to the expanded depth range. To change the upper and lower limits, first press the MENU key. Next, make certain the unit is in the manual mode, then press the up or down arrow keys until the "Set Chart Limits" menu appears as shown below. Now press the left arrow key to change the upper limit or the right arrow key to change the lower limit. After pressing the key, a screen similar to the one at the top of the next page appears. In this example, we're setting the upper limit. Use the up and down arrow keys to select the number, the right and left arrow keys to move to the next number. When the limit shows the desired depth, press the ENT key. The screen shown below appears. As you can see, the upper limit has changed from 0 to 35 feet. With the lower limit remaining at 60 feet, this gives a "zoom" of 25 feet. If you want to change the lower limit, repeat the above steps, press the right arrow key on the "Set Chart Limits" menu, and change the lower limit to the desired value.
