Reference Manual and Installation Manual
Correct installation is critical to the performance of the unit. It is vital to read this section of the manual and the
documentation that comes with the other parts before starting installation.
The NS3100 Multi can:
Drive external beepers or lights for the alarm and
countdown timer.
Send and receive data from other Northstar
instruments connected via NavBus. Settings for
alarms, units, calibration and backlighting are
shared (see section 8).
Warnings
The unit is waterproof from the front. Protect the rear of the unit from water, or else water might enter the
breathing hole and damage the unit. The warranty does not cover damage caused by moisture or water
entering the back of the unit.
Ensure that any holes that you cut will not weaken the boat's structure. If in doubt, consult
a qualified boat builder.
The choice, location, angle and installation of the transducers is the most critical part of the
installation. If they are not correct, the unit can not perform at its designed potential. If in
doubt, consult your Northstar dealer. Plastic through hull transducers are usually unsuitable
for wood hulls. If in doubt, consult a marine surveyor or marine engineer.
NS3100 Multi display unit
1 Choose a location for the display unit that is:
Easily seen and protected from damage.
At least 100 mm (4") from a compass and at least
500 mm (19.5") from a radio or radar antenna.
Away from engines, fluorescent lights, power
inverters and radio or radar transmitters.
Accessible from behind; the minimum clearance
required at the back is 50 mm (2") (see mounting
diagram).
With the back of the unit protected from moisture.
Send and receive NMEA data from
other instruments.
2 The unit must mount on a flat panel which is
less than 20 mm (0.75") thick. Stick the mounting
template in place. Drill a 50 mm (2") fixing hole
through the centre hole in the template. Note that
the template allows space around the unit for the
protective cover.

Insert the stud at the back of the unit through the
mounting hole. Hand tighten the fixing nut.
