Thisunit is so advanced, you can just press the "ON" button and let it do all the work. However, taking manual control enables you to open up a whole world of features not available in other sonars. [. . . ] To adjust the GRAYLINE level higher, press the right arrow key in the SENSITIVITY section on the keyboard. To decrease the GRAYLINE level, press the left arrow key in the SENSITIVITY section on the keyboard. Aftermaking the adjustments, the word "GRAY" will disappear after six seconds and the arrow keys will revert to sensitivityadjustmentagain. 11 34 PDF compression, OCR, web-optimization with CVISION's PdfCompressor $ENSfliV!TY I 8= ENABLE DIGITAL AVERAGING 9= DISABLE DIGITALAVERAGING The digital sonar in the X-50 is a highly sensitive sonar that gives extremely rapid updates of the water depth. Under most conditions, the bottom contour changes so rapidly that the depth display can appear to "jitter". In otherwords, the displaywill change the depth so quickly that it can be difficult to determine the actual bottom depth. To alleviate this situation, the X-50can averagethe bottom readings and place the result on the display. When the X-50 is firstturned on, averaging is enabled. To disable averaging, press the 9 key once the menu appears. To enable averagingonce again, press the 8 key. 10 = BATTERY BACKUPENABLED 11 = BATTERY BACKUPDISABLED Figure 8 GRAYLINE "orr" Figure 9 PROPER SETTING The X-50 has battery backed up memorywhich allowsit to retain all settings even if the power cable is removedfrom the unit. The batterycan be turned off or back on at anytime. To turn it on again, press iO. I stow [ RECALL -- STOP RESUME FAST STORE CHART SPEED When the X-50 is turned on for the first time, the chart scrolls at a pre-determined speed. If a higherspeed is desired, press and hold the FAST key in theCHARTsection ofthe keyboard until it runs at the desired speed. To slowthe display, press and hold the SLOWkey. Whenever either of these keys are pressed, the sensitivity bar at the top of the display will change to a dashed line and the word "CHT" will replace the word "AUTO" nearthe top of the display. If you press and hold the FAST key for example, the bar will start movingto the right, signifyingthatthe chart speed is increasing. There are 10 stepsof chart speed. When the horizontalbar reaches the far right side of the screen, the chart speed is at its maximum value. The X-50 will "flutter" signifying the maximumchart speed has been reached. lithe automatic mode or digital function is on, the maximum chart speed cannot be attained. (The chart barwill stop two steps from the far right and the audible tone will "flutter". ) Turning both the digital and the automatic mode off will allow the maximum chart speed to be attained. (Ten steps ofchartspeed are available ifthe digital and AUTOare off, Eight steps of charts speed availablewith digital and AUTO on. ) 12 = SCALE ON 13 = SCALE OFF Theupper and lower limit numberson the right side of thedisplaycan be turned on or offas desired. To turn them back on again, press 12. 14 = CALIBRATESPEED Due to variations in boat hulls and sensor mounting locations, the speedometer on the X-50 may need to be calibrated. The X-50 allows corrections to be enteredusingthe CALIBRATE SPEED command. To use it, press 2nd, DISC(COMMAND) until the CALIBRATE SPEEDfunction on the menu appears. Then press 14. 33 12 PDF compression, OCR, web-optimization with CVISION's PdfCompressor 2= GRAYLINECHECKERBOARD 3= GRAYLINELINES GRAYLINE can be displayedon theX-50with a checkerboard pattern or with lines and spaces. When the X-50 is shipped from the factory, the checkerboard pattern is enabled. To switch back, press the 2 key. 4 = SPEAKERVOLUME Thevolume of the speaker can be changed by pressing the 4 key. KEYS TO ADJUST VOLUME(the sensitivitykeysare used to adjust the volume ofthespeaker) and the speaker will begin beeping. Pressing the right arrow key will increase thevolume, theleft arrow key decreasesit. Thesensitivitybarwill move to the right or left, signifying the volume level. The speaker will stop beeping six seconds after the last key has been pressed. To view the chart speed withoutchanging it, press 2nd, STOP/RESUME. The sensitivity bar will disappear and the chart speed bar will replace it for a six seconds. At times it is desirable to stop or "freeze" the display to examine an echo before it scrolls off the screen. [. . . ] The temperaturewill be displayed immediatelyabove the digital bottom depth in degrees Fahrenheit. See Figure 22. Thetemperaturedisplay can be changed from degrees Fahrenheitto degrees Celsius. To change, press 2nd, 2 (F/C). A menu (see figure 23) will appear showing the current temperaturemode. To change modes, press 1 for degrees Fahrenheit, 2 for degrees Celcius, or CLEAR for no change. The menu will disappearafter six seconds if no keys are pressed, leaving the temperaturedisplay in the current mode. , I U!i[C1Iv--1. ]Fl;.
