Operating Manual 3
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
manual thoroughly to learn about the many features of your exciting new Novasail
product.
Introduction
NS350
Operating Manual4
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 Manual6
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 to start the device. A beep will be emitted.
• 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.
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.
Note
:
If the device does not turn on, you need to check if the battery is fully
charged, that the battery compartment is dry, and the polarity is correct.
Note :
Alkaline batteries should be used in order to result in a maximum
lifespan of 150 hours. When using a disposable battery, it is also recommended
to remove it if the device is not used for a prolonged period of time (in order to
avoid a possible leakage inside the battery compartment).
If using rechargeable batteries, low self discharge rate battery types are
preferred, because normal rechargeable batteries lose their stored energy more
quickly. Recommended batteries are SANYO ENELOOP, GP RECYKO+ or
UNIROSS HYBRIO. This kind of rechargeable battery will last for approximately
100 hours.

Operating Manual 7
Switching backlight on and off
• 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 sub-
mode required on the primary display by pushing and then the arrows
for the sub-mode selection. Then, display the selected sub-mode on
the secondary display using the button.
• You are free to choose another mode/sub-mode on the primary display.
Note :
Any sub-mode selection on the primary display will affect automatically
the secondary display when both displays are in the same mode.

Operating Manual8
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.
• Use the arrows to scroll 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 sensitivity is more suitable for race boats under medium wind and sea
conditions. Dinghy racers will appreciate this mode.
• MHL : Magnetic Heading Low sensitivity
Under Low sensitivity more subtile variations due to big waves and sudden gusts
are filtered.
WINd shift indicator mode
Used in Wind Shift Indicator (WIN) mode, the
NS350
displays numerical values
of the wind shifts allowing an immediate and effortless interpretation. To use this
mode, you need to memorize the tack lines on starboard and port.

Operating Manual 9
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 starboard then port or vice versa.
The WIN mode displays an angle in degrees which corresponds to the difference
between the tack line direction and the current magnetic compass heading of the
boat. It displays ’H’ (for Heading) in front of the value if the wind is heading, and
’L’ (for Lift) in front of the value if the wind is lifting. When sailing upwind, you need
to sail inside the lifts ’L’.
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 .
Note :
The first tack line memorized is by default considered to be the starboard
line. However, if this was the port tack line, the
NS350
will understand it
automatically.
