1 Introduction
The NS3100 Multi measures and displays speed,
water depth and water temperature. It can calculate
and display average speed, maximum speed, trim
speed, trip log (distance) and total log.
An installed NS3100 Multi usually has two parts:
The unit is powered from the boat’s power supply.
The NS3100 Multi is part of the Northstar family of
instruments for boats, which includes instruments
for speed, depth, wind and repeaters. These
instruments can be connected together to form an
integrated data system for a boat (see section 8).
For maximum benefit, please read this manual
carefully before installation and use.
How the transducer measures depth
The depth transducer generates an ultrasonic
(sound) pulse, which travels down through the water.
When the pulse meets the bottom, some of the
pulse is reflected back up towards the boat and is
received by the transducer.
The display unit.
Depth and speed / temperature transducers
which are attached to the hull and wired to the
display unit.
The NS3100 Multi display unit
The display unit analyses the reflections from each
pulse. It removes unwanted reflections (from bubbles
and other objects) and calculates the depth by
measuring the time between sending the pulse and
receiving its echo.
How the transducer measures speed
The speed transducer has a small paddlewheel
which spins as the boat moves through the water.
The transducer measures how fast the paddlewheel
is spinning and calculates the boat speed by
averaging several measurements.
Cleaning and maintenance
Clean the display unit and any plastic transducers
with a damp cloth or mild detergent. Avoid abrasive
cleaners, petrol or other solvents.
When repainting the hull, cover or remove any
visible transducers. Depth transducers may be
coated with a thin layer of antifouling paint; gently
sand off any previous paint first.

2-1 Turn on and off
2-2 Basic operation
Backlight Level 2
Turn the unit on and off with the auxiliary power
switch on the boat. The unit does not have its own
power switch. When you turn it off, any settings you
have made are retained.
If the word SIM flashes at the bottom, right of the
display, then the unit is in simulate mode (see section
2-5) .
The keys
The unit has four keys, labelled and . In
this manual:
Press means to push the key for less than one
second.
Hold for two seconds means to hold the key down
for two seconds or more.
Press one key + another key means to push both
keys together.
Set backlight level for screen and keys
You can set the backlight to one of four brightness
levels or off. Press once to display the current
backlight level, press again to change the level:
Change the items displayed
The display can show two values at once, one in the
top part of the screen and one in the bottom. If an
item displays as dashes (— —) then it means that the
value is outside the range, for example the depth
might be too deep or unknown.

screen, press

The NS3100 Multi can be set to sound an alarm
when the water is too deep or too shallow (see
sections 5-2 and 5-3). When the alarm sounds, the
internal beeper sounds, the symbol on the display
flashes and any external beepers or lights operate.
Simulate mode allows you to become familiar with
the unit off the water. In Simulate mode, the NS3100
Multi functions normally except that the transducers
are ignored and the unit generates this data
internally. The word SIMULATE flashes at the bottom,
right corner of the screen.

Press
to mute the alarm. The alarm stays muted
until the depth becomes returns to the pre-alarm
condition or is within the alarm parameters. The
alarm will sound if the depth becomes too deep or
too shallow again.
To turn Simulate mode on or off:
1 Turn the power off.
2 Hold down
