[. . . ] Note that some polarized glasses can affect your view by causing a rainbow or prism to appear; if so, tilt the unit slightly. ) Though it includes sophisticated electronics, the LCR 100 is tough enough to take the pounding punishment of rough seas or a race across the lake. Completely waterproof - even saltwater-proof - your LCR 100 will provide you with many years of thoroughly reliable operation. USING THE BUILT-IN SIMULATOR The LCR 100 includes a built-in simulator that helps you learn to use your new equipment. The simulator displays a typical underwater scene, and lets you practice with the controls. The unit must be turned off before you start the simulator. [. . . ] Using Zoom; Factory setting: OFF Zoom provides an up-close view. To activate it, select Zoom and press ON-OFF: The Zoom view initially begins at the surface; pressing the Up or Down arrow adjusts Zoom depth. The range of the display is shown when Zoom is on. The Zoom range depends on the current Depth Range: 7 1/2' in the 15' and 30' Depth Ranges, 15' in the 60' and 120' Depth Ranges, and 30' in the 180' to 600' Depth Ranges. (Metric display: 3m in the 6m and 9m ranges, 5m in the 15m and 30m ranges, and l0m in the 45m to 185m ranges. ) Remember: If Zoom is the last function selected, you can use the arrow buttons to adjust the Zoom depth or ON-OFF to switch Zoom on and off without having to press SELECT first. The word zoom will be shown on the display when the zoom function is enabled. 5. Using Bottom-Lock; Factory setting: OFF Bottom-Lock provides an up-close view like Zoom, except that in this case the zoomed view automatically moves up or down to stay on the bottom. The range of the display is shown when Bottom-Lock is on. This is an ideal feature for finding structure or locating fish near the bottom. Remember: If Bottom-Lock is the last function selected, you can use the ON-OFF button to switch Bottom-Lock on and off without having to press SELECT first. 6. Setting Display Speed; Factory setting: One level below maximum The LCR 100 display is "updated" (advances across the screen) as you move through the water. The speed at which the display is updated depends on the Display Speed setting. To adjust it, select SPEED, and press the Up arrow for a faster setting or the Down arrow for a slower setting. In general, higher Display Speed settings provide faster updates, while slower Display Speeds provide more detailed information. 7. Setting Depth Range; Factory setting: ON (Automatic) When you turn the LCR 100 on, it finds the bottom, sets the ideal Depth Range, and automatically adjusts the Depth Range (to as much as 480'/150m) as the depth changes. In this "Auto Depth Range" mode, the bottom is blacked-in for easy-to-understand readings. If you prefer, you can turn Auto Depth Range off. Select RANGE, press ON-OFF, and adjust the Depth Range with the Up or Down arrow key. You can set Depth Range up to 600'/185m. In this "Manual Depth Range" mode, the bottom is not blacked in. This lets you see a "second return, " which is preferred by some fishermen because the width of the second echo can indicate bottom hardness.
