Introduction With the NS350, you can find a magnetic compass along with the allessential race functions : wind shift indicator, direction, tactical compass and race timer. Compact (125mm x 80mm x 26mm) and intuitive, the NS350 is lighter (190 grams) than any existing system, wired or wireless. It is also waterproof and robust, being made of bombproof polycarbonate and anodized aluminium. Powered with only one AA battery, the NS350 gives sailors accurate information for over 150 hours and can be installed in minutes. We hope you enjoy sailing with the NS350, and encourage you to read this...

Installation The mounting location should be as far as possible from any magnetic objects to avoid any interference with the compass sensor. The NS350 should be mounted as close as possible to the vertical and horizontal planes. Operating Manual

Operations Switching power on and off • Make sure the battery is installed with the correct polarity and has enough remaining power (positive pole inserted first). Press and hold for more than 4 seconds until the screen displays OFF and the sequence “3”, “2”, “1” is finished. A beep will be emitted when the device turns off. to start the device. A beep will be emitted. The device will turn off automatically when it remains in the horizontal position for more than 3 minutes. A beep will be emitted 3 seconds before it turns off. If the device does not turn on, you need to check if the battery...

• Press and hold for more than 1 second until the icon is displayed on the screen. If the OFF sequence starts, simply release the button before the sequence “3”, “2”, “1” is finished. • To turn off the backlight, press and hold for more than 1 second until the icon disappears from the screen. Note : When you press and hold the select button to switch on/off the backlight, you will not make any selection and therefore will not change any parameter. Switching modes and sub-modes • To have two different separate readings, first choose the mode and submode required on the primary display by...

Operations Magnetic Heading compass mode To win races you need to react to even small wind shifts. The NS350 digital compass delivers precise and reliable heading information to help you to tack and gybe at the most suitable times. The sensitivity of the compass can easily be adjusted to High, Medium or Low by scrolling through the sub-modes. • Sub-modes of the Magnetic Heading compass : • MHH : Magnetic Heading High sensitivity When sailing with light winds and flat seas, High sensitivity allows you to appreciate very small wind variation. • MHM : Magnetic Heading Medium sensitivity Medium...

Memorization of the tack lines : • Sail upwind to your optimal VMG. • “D 1” is displayed on the data line of the lower screen. • Press to use the current magnetic compass heading as the one of the tack line directions. • The wind shift value is immediately displayed. • Press the arrows - + to display “D 2” on the data line of the lower screen. • Sail upwind to your optimal VMG on the other tack line. • Press to use the current magnetic compass heading as the other tack line direction. Note : The sequence of memorization of the tack lines on starboard and port is not defined. You can do...

Operations fig.1 WIN mode diagram when sailing on starboard Wind direction Starboard tack line Port tack line Tack indicator mode : TAK Used in tack indicator mode (TAK), the NS350 displays : • The time elapsed when the boat is sailing into a heading wind compared to the average wind direction. • The angle (bar graph) with the mean wind direction into a lifting wind. This mode is particularly useful in order to minimize the time spent in a heading wind, allowing an immediate action (tacking). Note : To use this mode, the tack lines on starboard and port must have been memorized in WIN...

fig.2 TAK mode display when sailing with a lift wind on starboard Wind lift: 21degrees fig.3 TAK mode display when sailing with a lift wind on port Wind lift: 11 degrees When the boat is in a heading wind, the time spent in seconds is displayed. If the value is greater than the threshold value set in SETUP mode, the timer value and ’TAK’ are displayed alternatively (see “SET mode”, page 14). If the boat goes

Operations back to the lifting and the heading wind area again, the timer will restart upcounting from 0. The maximum value of the timer is 90 seconds. fig.4 TAK mode display when sailing with a head wind Head : 15 degrees When sailing down-wind, (Port) or (Starboard) will be displayed on the screen, followed by the the value of the deviation from the wind direction. Roll angle indicator mode : ROL Used in Roll angle indicator (ROL) mode, the NS350 displays the roll angle of the boat. The angle range can vary from 0 to 70 degrees; if the angle is greater than 70 degrees, the value blinks...

This mode offers a countdown timer which can be set from 1 to 9 minutes. When counting down, a short beep sounds : • each minute until the last minute • each ten seconds until 10 seconds • each second until the start time At the start time : • a long beep sounds • the timer starts counting the race duration in minutes and hours Adjust, start and stop the TIMER : • Adjust the timer value with the arrows - + • Press © to start and stop the TIMER. Resynchronize the TIMER to the nearest minute : When the TIMER is running, at any time you can resynchronize to the upper or lower minute • Press...
