User manual LOWRANCE X67C ICEMACHINE-

[. . . ] You should be familiar with those basic functions before you head for the ice. A good place to start is the Basic Sonar Operation section, beginning on page 27, or the one-page Basic Sonar Quick Reference, on page 34. This addendum covers the basic ice fishing functions and any other operational changes that may have occurred since the manual was published. In addition to the instructions found here, be sure to read the PPP-15 instruction booklet, part number 988-0147-871. [. . . ] Press MENU| to ICEMACHINE MODE|ENT|EXIT and the Ice Flasher appears. (To leave IceMachine mode and return to normal operation, just repeat step 2. ) Flasher Page Menu, with IceMachine Mode command highlighted but turned off (box not checked). The following figure shows the various components of the Ice Flasher page display. Bottom ColorLine shows hard bottom Temperature Bottom Signal indicator Surface signal Surface clutter signal Small fish or bait signals Digital Depth Depth Range Scale Bigger fish signal at 15 feet. Sensitivity Control Bar Echo Strength Color Scale Battery capacity gauge Ice Flasher page. 4 Sensitivity Sensitivity and Auto Sensitivity are described in detail in the manual on page 55. To adjust sensitivity on the Flasher or Ice Flasher page, simply press to increase sensitivity and press to decrease sensitivity. The changes are displayed on the horizontal Sensitivity Control Bar. The Echo Strength Color Scale also changes as you adjust sensitivity. Important: Setting Sensitivity for Ice Fishing The IceMachine's basic operation is pretty easy, right out of the box. If you're a sonar novice, try operating the unit with the automatic factory default settings until you get a feel for how it's working. As you're learning the basics however, Sensitivity is the one important setting that you should adjust while ice fishing. We strongly recommend you try the following method for "tuning" your sensitivity to match the current water conditions. It will help you see your bait, cut through any clutter in the water and dramatically show fish when they move in to check your offering. As you learn to interpret the signals on the flasher screen, you'll be able to modify your presentation based on how fish react to your lure. Start with your IceMachine showing the Ice Flasher page, in the default IceView color mode. Drop your lure five to 10 feet directly below the transducer. You should be able to follow the fall of the bait on the flasher screen. Use the arrow keys to turn the sensitivity up or down until the lure is barely visible as a black or blue signal band on the screen. When a fish approaches the bait, its signal will stand out from the lure because it will be a moving signal that is wider and a brighter color than your lure. ColorLine ColorLine is described in detail in the manual on page 43. ColorLine changes will be reflected in the Echo Strength Color Scale. This scale considers both sensitivity and ColorLine and then shows you the relationship of signal strength to signal color. From the Ice Flasher Page, press MENU| to COLORLINE|ENT. 5 2. Press to decrease ColorLine; press to increase ColorLine. When it's set at the desired level, press EXIT. ColorLine distinguishes between weak and strong sonar signals by "painting" them with different colors. You can adjust ColorLine to suit your personal viewing tastes.
