Installation
Location
The NAVMAN M100 is designed for above or
below deck installation. Select a position that is:
• At least 300mm from a compass
• At least 500mm from any radio
• Easy to read by the helmsman and crew
• Protected from physical damage
• Accessible to electrical cable connections
• Protected from water spray reaching rear
of instrument.
Mounting
The mounting surface must be flat. Use the
template to set the centre of the fixing hole.
• Drill a 32mm (1.25”) diameter mounting hole
through the bulkhead.
• Remove the fixing nut. Peel the protective
paper off the foam gasket and attach the
gasket to the rear of the instrument.
• Insert the instrument through the bulkhead.
Hand tighten the nut and then finally tighten
with a spanner. Do not over tighten so that
the water sealing ability of the gasket is
damaged.

• Connect the 4 pin Fuji connector to the
Speed and Temperature transducer.
• Connect the RCA phono connector to the
depth transducer cable connector. Do not
cut or shorten the depth transducer cable.
Extension cables are available if the
transducer cable is too short.
• If you are not using a repeater or you do not
intend to provide NMEA data to another
instrument then insulate the bare wire end
of the blue cable.
Wiring Connection
• Keep electrical and transducer cables away
from alternator or other noise generating
electrical cables. Avoid connecting the
instrument to power circuits that share
loads with ignition, alternators, inverters and
radio transmitters. Electrical power supply
connections should always be as short as
possible.
• Connect the red wire to the positive supply
via a 1 amp fuse or a 1 amp circuit breaker.
Connect the black wire to the electrical
ground (negative terminal of battery).
A 1 amp fuse will provide protection for up
to five 100 series instruments.
Multiple Instruments
TheNAVMAN M100 may be usedasanindividual
instrument or connected with a number of other
100 series instruments to the 100 series
repeater or to other instruments accepting
NMEA 0183 data.

Calibration Procedures
Note:
If the speed and depth readings flash, this
indicates that the calibration values have
been lost. To correct this, check the depth
units, alarm values, keel offset, speed units
and the speed calibration.
Keel Offset
The NAVMAN M100 will normally display the
depth of water below the face of the transducer.
You may introduce a negative keel offset equal
to the distance from the transducer to the bottom
of the keel to display the depth of the water
below the keel. A positive offset equal to the
distance from the waterline to the transducer
can be used to display the total depth from the
water surface to the bottom. This is often called
a waterline offset.
Follow the Secondary Functions chart to reach
Keel Offset mode.
Use the or key to set the required value.
When the required value is displayed press the
key. The value will be stored in memory.
Note:
When the depth units are changed the
keel offset value will automatically be
recalculated and displayed in the new units.
Transducer Setting
Three values of transducer setting can be
selected (1 to 3). A setting of 3 provides the
maximumimmunity to turbulence, surface clutter
and transducer ringing at the expense of shallow
water performance under 4 feet. A setting of 1
enables the M100 to work in water as shallow
as 1.8 feet at an increased susceptibility to
turbulence.Atasettingof2,theM100 will properly
display depths down to 2.9 feet. The default
setting is 2.
To enter the transducer setting into memory and
exit, press the key.

Speed Calibration
Speed Comparison Method
Use the following sequence to adjust the speed
displayed to match that of another craft or the
speed displayed on a GPS receiver.
Follow the Secondary Functions chart to reach
Speed Calibration mode.
To increase reading press the key.
To decrease reading press the key.
To enter the calibration setting into memory and
exit press the key.
Note:
When the speed calibration is adjusted the
trip log and the average speed will be reset.
Log Calibration Method
Set the log to zero and travel a known distance
between two points. If there is any tidal current,
you should travel the course in both directions
and use twice the known distance. Try to avoid
the situation where the current is flowwing at
right angles to the course, or if this cannot be
avoided, make sure that the boat speed is at
least ten times the speed of the current.
You may calculate a correction factor as follows:
Known distance
correction factor = distance from log
For example, if you have travelled over a known
distance of 1 mile but your log reading is 0.80,
the correction factor is 1.25. Therefore, your
correct boat speed will be the indicated speed
multiplied by 1.25.
Enter the simulation mode by holding down the
key at power up, When speed is selected in
the simulator mode the display will indicate a
fixed calibration speed. With the factory default
calibration this speed will be 10.0 knots.
Follow the Secondary Functions chart to reach
Speed Calibration mode.
Use the to set the displayed speed to the
new value. For our example, assuming we
started with the factory default calibration, this
new speed would be 10.0 x 1.25 which is 12.5
knots.
To enter the calibration setting into memory and
exit press the key.
To exit simulation mode, remove the power and
then hold the key at power up

Troubleshooting Chart
No display: Check DC power connections and DC polarity with voltmeter. Voltage must be
between 10.7 and 16.6 volts.
No speed reading:
1. Remove speed impellor from skin fitting, spin paddlewheel manually and check
for reading.
2. Check for fouling on paddle and skin fitting.
3. Check for break in cable.
Low or high speed reading:
1. Check calibration.
2. Inspect for damage to paddlewheel or fouling of fitting or paddle.
Erratic speed reading:
1. Is there clear water flow over paddlewheel ?
2. Is paddlewheel aligned fore and aft correctly ?
No, or inaccurate temperature reading:
1. Check calibration
2. Check for break in cable.
No depth reading (--) at all depths:
1. Check transducer for growth or multiple coats of paint.
2. Check the transducer cable for cuts and sharp bends.
3. Substitute the transducer with a known good transducer hold it over the side of
the boat into the water and see if instrument functions. This isolates cause of
problem (transducer or instrument).
Erratic depth readings (while moored):
Check transducer for growth or multiple coats of paint.
Erratic depth readings (while underway):
Cavitation (air) under the face of the transducer. Review installation and reinstall
if necessary.
When power is applied display digit counts up or down:
See the section on Simulation Mode.
Erratic readings when engine is running:
1. Reroute power and transducer cables away from ignition wires and battery
cables.
2. Add feed-through filter capacitor on the positive terminal of the ignition coil.
3. Add alternator whine filter to alternator.
4. Replace spark plug wire with resistive type.
Simulation Mode If the speed is not changing and reading around 10kts regardless of boat speed
then the instrument is in simulation mode.
