To viewthese groups, simply press the WINDOWSkey, then repeated press the down arrow key. [. . . ] The letters "Man" appear in the upper left cornerof the display, indicating the unit 9 iftheconepassesover a fishin shallowwater, thesignal displayedon the X-55 maynot arch at all. This is due to the narrowconediameter and the resolution limitations of the display. FISH ARCHES Fish arches are createdwhenthecone of sound passes over a fish. The distance to afish whentheconefirst strikes it is shown as "A" onthe next page. Whenthecenterofthe cone strikes the fish, the distance is shorter as shown "B". As the cone leaves thefish, thedistanceincreases again as shown in "C". 12 29 36 Very small fish probablywill not arch at all. Medium sized fish will showa partial arch, or a shapesimilarto an arch if they're in deep water. Large fish will arch, but turn the sensitivity up in deeper waterto seethearch. Because ofwaterconditions, suchas heavy surface clutter, thermoclines, etc. , the sensitivity sometimes cannot be increased enough to get fish arches. Oneof the bestwaysto getfish archesisto expand or"zoom"asegment 28 PDF compression, OCR, web-optimization with CVISION's PdfCompressor is in the manual mode. To turn Automatic on, press the AUTOkey again, then pressthe right arrow key. SENSITIVITY However, therearetimeswhenyou maywanttoturn the ASPfeatureoff. Thisallowsyoutoviewall incoming echoesbefore theyare processed by the ASPfeature. The sensitivity key on theX-55 controls the ability of the unitto pick up echoes. A low sensitivity level excludes much ofthe bottom information, fish signals, and othertarget information. High sensitivity levels enables youtoseethisdetail, but itcanalso clutterthescreen with many undesired signals. Typically, the best sensitivity level shows a good solid bottom signal with Graylineand somesurfaceclutter. Whenthe X-55 is in the Automaticmode, thesensitivity is automatically adjustedto keep a solid bottom signal displayed, plus a little more. However, situations occur where it becomes necessary to increase or decreasethe sensitivity. This typically happens when you wish to see more detail, so an increase in sensitivity is indicated. The procedureto adjust it isthesamewhethertheunitis in the automatic or manual mode. The sensitivity menu has left and right arrows, plus a horizontal bar graph. The number above the INC arrow also showsthe percentage of sensitivityin use. As you press the key, the menu's bar graph will grow wider and thepercentage will increase in value. You canalso seethedifference on thechart record as it scrolls. When the sensitivity is atthe desired level, release the key. Tochange the ASP level, press the MENU key five times. [. . . ] The percentage of contrast in use changesas the arrow keys are pressed. Afteryou've madetheadjustment, pressthe CLEARkeyto erase the menu. ALARM MUTE Wheneithertheshallowordeepalarm istriggered, an audiotone sounds. A differenttone soundsfor the shallowthan thedeep alarm, thus letting you know which alarm is sounding withoutlookingat the unit. Once a depth alarm is triggered, it keepssounding until you changedepth. [. . . ]
