Use the arrow keys to select the desired unit of measure, then press the PWR key to clear the menu. Depth menu controls the unit of measure used to show depth. 39 TEMPERATURE UNITS OF MEASURE This unit can show the temperature (if a temperature sensor is attached) in degrees Fahrenheit or Celsius. To change the unit of measure, press MENU DOWN until the SYSTEM menu appears. Press UP ARROW, then press MENU until the TEMPERATURE menu appears. Use the arrow keys to select the measurement unit, then press PWR to clear the menu. Temperature unit of measure menu. SPEED and DISTANCE LOG UNITS OF MEASURE The speed and distance log can be displayed in statute miles (MPH), Nautical miles (knots), or Metric (kilometers per hour) if a speed sensor is attached. To change the unit of measure, press MENU DOWN until the SYSTEM menu appears. Press UP ARROW, then press MENU until the SPEED/LOG menu appears. Use the arrow keys to select the desired measurement unit, then press PWR to clear the menu. Speed menu. 40 RESET DISTANCE LOG You can reset the distance log to zero with this command. Press MENU DOWN until SYSTEM appears, then press UP ARROW. Press MENU until the RESET LOG menu appears. Press UP ARROW and the log returns to zero. Press PWR to clear the menu. Reset Log menu. PRESET UNIT (reset all options) This command is used to reset all features, options and settings to their original factory defaults. This is useful when you have changed several settings and want to return the unit to basic automatic operation. Press MENU DOWN until SYSTEM appears, then press UP ARROW. Press MENU DOWN until the PRESET UNIT menu appears. Press UP ARROW and the unit will turn itself off and reset all options. Turn the unit back on by pressing PWR. Preset Unit menu resets all options to the factory settings. 41 SYSTEM INFO To show the operating software system information, press MENU DOWN until the SYSTEM menu appears, then press UP ARROW. Press MENU DOWN until the SYSTEM INFO screen appears. Press PWR to clear the screen. System Info screen. SIMULATOR This unit has a built-in simulator that shows a simulated bottom signal with fish signals. This lets you practice with the unit as if you were on the water; all features and functions of the unit are usable. A message appears occasionally to remind you that the simulator is on. To use the simulator, press DOWN MENU repeatedly until the SYSTEM menu appears, then press UP ARROW. Press DOWN MENU until the SIMULATOR menu appears. Now press UP ARROW to turn it on, and press PWR to clear the menu. Repeat the above steps to turn it off, or you can simply turn the unit off and back on again. Simulator menu. 42 NOTE: If you turn on your unit before attaching a transducer, it may enter a demo mode. The words "demo mode" flash on the bottom of the screen and a sonar chart plays much like the Simulator feature. Unlike the simulator, the demo mode is for demonstration only, and will automatically stop as soon as you turn on the unit with a transducer attached. The simulator will continue to function normally. CHART SETUP The Chart Setup menu lets you further customize the display. The size of the digital numbers for the depth, temperature, speed and distance log can be customized from this menu. The depth scales shown on the right side of the screen can be modified, and the Fish Reveal modes can be turned on or off. To enter the Chart Setup menu sequence, press MENU DOWN until the CHART SETUP menu appears. Press UP ARROW and then you can use the menu keys to cycle through the chart setup menus. Chart Setup menu. LIMIT SEARCH The Limit Search command helps you maintain maximum chart detail when you are moving fast in deep water (about 200 feet.) When turned on, Limit Search prevents the digital sonar from over-riding the sonar chart's depth range setting. Limit Search does this by preventing the digital sonar from slowing down the ping speed as it automatically searches for and tracks the bottom. The default setting is off, and this should fit most freshwater fishing situations. High boat speed and slow ping speed (caused by the deeper bottom) can reduce the screen refresh rate. This in turn can reduce the amount of 43 detail seen on the sonar chart. Try this command only if you are in deep water, traveling at high speed, and notice a reduction in detail on the sonar chart. When Limit Search is turned on, the digital sonar will limit its search for the bottom to the depth range you have set for the sonar chart. NOTE: Turning Limit Search on can cause the digital sonar to lose the bottom in some situations. The digital depth will flash if that occurs. The sonar chart must be in manual depth range mode to use the Limit Search command. To switch from auto depth range to manual, press MENU until the RANGE menu appears. Use the arrow keys to select the desired range. When you're finished, press PWR to clear the menu from the display. Next, press MENU DOWN until the CHART SETUP menu appears, then press UP ARR...
