User manual LOWRANCE X67C ICEMACHINE-

[. . . ] 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. It will tell you how to set up the ice fishing power pack and mount the X67C. Addendum I Topics discussed in this document include: Introduction to IceMachine Mode · · · · Your unit now has five pages that display sonar information. [. . . ] At right, the Full Sonar Chart is shown. You access the various page displays by pressing the ENT/PAGES key. To return to a previous page, simply press ENT repeatedly until the desired page appears again. (It serves multiple functions, but we'll refer to this key in the text as simply the ENT key. ) NOTE: We use a type of "menu shorthand" to describe how to work your sonar. To understand our typographical and instruction conventions, see the segment How to Use this Manual on pages 3-4 in the X67 manual. From the Full Chart Sonar page, press ENT|ENT|ENT to switch to the normal Flasher page. (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 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. 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. This scale considers both sensitivity and ColorLine and then shows you the relationship of signal strength to signal color. When it's set at the desired level, press EXIT. ColorLine distinguishes between weak and strong sonar signals by "painting" them with different colors. The center figure shows a lower ColorLine setting and at right, a higher setting. These black and white illustrations don't show it, but the far left band on the Echo Strength scale is black, followed by blue, green, yellow and at the far right, red. In the Ice Flasher, the weakest signals are shown in black and the strongest signals show as red. [. . . ] Signal width also increases as a fish approaches the center of the sonar cone. Ice Flasher Options Split Zoom Display Mode When ice fishing season arrives, you're often searching for fish that are hugging the warmer water at the bottom of the lake. When walleye or perch are holding right on the bottom, your X67C IceMachine can separate those fish from the bottom with a remarkable Split Zoom display mode. In this mode, the right half of the flasher screen operates normally with the surface at the 12 o'clock position and the bottom of the depth range at the 6 o'clock position. The left half of the flasher zooms in on the six feet just above the bottom, with the bottom at the 6 o'clock position and 6 feet above the bottom at the 12 o'clock position. [. . . ]
