[. . . ] To enter Simulator mode, press the POWER-MENU button to turn on the RF20, wait until you see the Start-up screen, then quickly press the RIGHT Cursor Button. Once you are in Simulator mode, the display will show the word Simulate, and then, after two seconds, will show simulated data. To activate the menu system, press the POWER-MENU button; the first time you do this after power up, the Sensitivity menu choice will appear. Once the RF20 has been powered on, pressing the POWER-MENU button will display the last menu choice viewed. press the POWERMENU button repeatedly to access other SmartCast menu choices , one at a time. When a menu choice is on the display, use the RIGHT and LEFT Cursor buttons to adjust the menu settings. Menus are automatically removed from the display after several seconds. All settings return to factory defaults when the SmartCast is turned off. Select a higher number to show weaker sonar returns on the display, or a lower number to remove clutter from the display. Adjusting Sensitivity also affects how sonar returns are identified as Fish ID Symbols - more fish will be detected at the highest setting of 5, fewer at the lowest setting of 1. When in automatic, the lower range will be adjusted by the unit to follow the bottom. NOTE: In manual operation, if the water depth is greater than the depth range setting, the bottom will not be visible on the display. Depth scale changes or signal loss will cause lines with missing detail and/or abrupt changes in the graphed bottom. When the Depth Range is set to Auto, the depth is set to keep the bottom in the lower third of the screen. The screen image jump shown here is due to an automatic change in depth. New returns graphed at a different scale will not match up with the historic data already graphed at a higher or lower scale. Vertical lines can also occur as the radio signal from the RSS is lost and then regained in rough water conditions. Select either Off to view "raw" sonar returns, or On to view fish symbols. Fish ID uses advanced signal processing to interpret sonar returns and will display a Fish Symbol when very selective requirements are met. There are two versions of the RSS that are available at your local tackle dealer, major outdoor retailers, or at the site www. you also have the option to purchase additional Channel A or Channel B RSS units. When using the A or B version of the RSS, make sure to select the appropriate channel using the CHANNEL menu choice.
