The tachometer and speedometer each have three pushbuttons, which allow the different functions of each instrument to be activated. M Mode Button Down Up Button Button CORC113 Sport 4-15 Nautique Sport Sec 4.qxd 11/19/04 4:02 PM Page 16 Section 4 Refer to Standard Dash Pod in this section for additional information on gauge operation. Speedometer / Depth Sounder The Serial Bus Speedometer / Depth Sounder provides both the functions of a speedometer and a depth sounder. The analog speedometer looks like a standard analog device but is actually a digital instrument. On small pointer movements you may occasionally see the pointer moving in the one-third degree "steps" that represent the accuracy of the instrument.

Nautique Sport Sec 4.qxd 11/19/04 4:02 PM Page 17 Controls and Indicators Speedometer Function The speedometer measures the water pressure in the pitot tubes when power is first turned on. This measurement is subtracted from later readings to correct for the pressure caused by the weight of water over the pitot pick-up. For maximum accuracy, the boat should not be moving when the key is turned on, especially in a re-start condition. If the boat is moving, the pressure in the pitot will be greater than normal, resulting in the speedometer reading low. The system is designed to operate with two pitot pick-ups for speed sensing. The speed displayed is based on the pitot with the highest pressure. On the speedometer LCD display, the active pitot sensor will be identified with a “P” or “S.” It is normal to see the display switch between the port and starboard pitot sensors, especially in high-speed turns. Both pitot sensors are continuously monitored, and blockage in either sensor will be detected. If a sensor becomes blocked, the system will switch to the clear pitot sensor. An “XX” will flash in place of the “P” or “S” on the speedometer LCD to indicate which sensor is blocked. Clean the pitot sensor to restore normal operation.

The speedometer is calibrated at the factory however, significant variations can occur due to changes in location. Therefore, the speedometer can be easily calibrated to a known reference such as a radar gun, measured course, or GPS. The LCD will display: Calibration Display CORC116 When the unit is operating in normal mode (i.e. pitot status information on the LCD), push and release M to put the speedometer in the calibration mode. Push and hold M down for at least two seconds, the LCD will show “AdJUST.” Calibration Display CORC117 Run the boat at a constant 30 MPH as measured by the GPS, radar, or closed coarse. Adjust the speedometer pointer by pressing and until the speedometer matches the known speed. When finished, press M to exit the adjustment screen. The operator has the option of saving or canceling the adjustment procedure. The options can be selected using and . To save the calibration setting, press and hold M for two seconds when the display shows “SAVE.” 4-18 Correct Craft, Inc. Nautique Sport Sec 4.qxd 11/19/04 4:02 PM Page 19 Controls and Indicators Save Display CORC118 To exit the adjustment procedure without saving, press and hold M for two seconds when the display shows “NO SAVE.” Multiple runs in opposite directions may be necessary to compensate for errors due to water currents. No Save Display CORC119 Depth Sounder Function To display depth information on the LCD push and release the M until the display shows the depth. The depth sounder is turned on and off with the ignition switch. The depth sounder can also be turned off at any time, while in depth display mode, by pressing and holding M while the depth sounder counts down a three second delay. The depth display will then indicate “OFF.” Off Display CORC120 Press and hold the M to turn the depth sounder back on. Sport 4-19 Nautique Sport Sec 4.qxd 11/19/04 4:02 PM Page 20 Section 4 When there are no alarm conditions, the water depth is displayed. If the signal is weak or lost, or there is no transducer connected, the display will alternate between the last known depth and three horizontal bars. Depth Display CORC121 Canceling Depth Alarms A depth alarm warning can be temporarily canceled by pressing both and on the speedometer, simultaneously. After one minute, the alarm will resume if the condition that caused the alarm is not corrected. The operator can cancel the alarm as many times as necessary, until the condition is corrected. The depth alarm warning will replace any information on the LCD screen. Canceling the alarm w...
