EMC Conformance
All Tacktick equipment is designed to the best industry standards for
use in the recreational marine environment. The design and
manufacture of Tacktick equipment conforms to the appropriate
Electromagnetic Compatibility (EMC) standards. Correct installation is
required to ensure that performance is not compromised.
Important
Due to the wireless communication systems used in Micronet
instruments they are only recommended for use on boats up to 14
meters (45 ft.) which are of glass, carbon, or wooden construction.
Like any other Electronic instruments your Micronet system is
designed to serve only as an aid to navigation and it remains the
skippers responsibility to maintain a permanent watch and be aware
of developing situations.

1 - Information
1.1 Introduction
Your Micronet instrument is powered for life by the environment.
Although feature packed and highly visible in all conditions, current
demand is so low, and the supply so efficient, that the solar-powered
display is self sufficient. Combined with other instruments in the
Micronet range this display becomes part of a complete navigational
system.

1.3 Power Management and Battery Life
What makes your mn100 instrument possible is Tacktick’s
revolutionary approach to power management. By reducing the
amount of power being used by the electronics and maximizing the
potential of the sun to provide power, a mn100 instrument becomes a
virtually perpetual device.
Power status is indicated by two icons on the instrument display:
Battery Level
and Charge Rate
Used together these icons will show the condition of your instrument’s
power supply.
Operation
5
2 – Operation
Important:
Ensure that the “Auto Network” procedure described on the yellow
instruction sheet and full Setup and Calibration has been performed
correctly before attempting to use your Micronet instruments for
navigation purposes.
2.1 Instrument Display Information
mn100 Dual Digital Display

If there is no boat speed or change in heading registered on the
system for a period of 12 hours your Micronet instrument will switch
off to conserve power. A “POWER SAVE” alarm will sound before the
instrument system is switched off. Pressing any button within 10
seconds of the alarm sounding will allow the system to remain
switched on.
Backlighting will automatically shut down/off when operated in
daylight.
Artificial light WILL NOT recharge the battery. Placing
your Micronet instrument close to an artificial light will
seriously damage the instrument. Only recharge in natural
daylight.
Applying External Power
In cases where instruments are mounted permanently below decks it
will be necessary to apply an external power source to prevent
complete discharge of the built in battery.
Connections on the rear of the instrument allow a 9V to 24V DC power
source to be connected. Connections can be made to the vessels DC
system or a 9V battery pack may be connected. It is recommended
that permanent connection is only made when the instruments are
permanently fixed to the vessel and not when the clip brackets are
used.
Connection to a 9V (PP3) battery will fully recharge the internal
battery over a period of 24 hours.
1.4 Safety and Disposal
Your Micronet instrument contains Manganese Lithium Dioxide
batteries which should be disposed of correctly. Do not dispose of any
instrument in domestic waste. Refer to regulations in force in your
country.
If in doubt return the instrument to Tacktick Ltd. for correct disposal.

and
Flashing
It is recommended that the
instrument be left in daylight for
some time for the battery to
recover, or charge from an
external 9 - 24V power source. A
fully discharged battery will recharge in approximately 12 hours
of direct bright sunlight.
If using the instruments at night power usage can be reduced
dramatically by switching the Backlighting to level 1 or Off. If
Backlighting is not required on instruments located below decks it is
best to set them to “Local” Backlighting control (see page 26 -s31) so
that power is not being wasted in instruments which may not be
visible from the one being viewed.
* If the internal battery is fully charged then it does not matter
how much the instrument is subjected to bright sunlight no further
charging is required and the Charge Rate Indicator will remain low.
If the instruments are to be stored for a long period of time before
next use (Over Winter) ensure that the batteries are fully charged
before storage. If necessary connect to a 9 to 24v power supply for
24 hrs prior to storage.

6 Maintenance and Fault Finding
6.1 Care and Maintenance
All Micronet products are totally sealed against water and are not
serviceable. Any attempt to take a Micronet product apart will
invalidate the warranty.
To clean, use only a damp, soft cloth. No detergents, solvents or
abrasives should be used. To avoid damaging a Micronet display unit
we recommend storing in the supplied soft pack when not in use.
If the instruments are to be stored for a long period of time before
next use (Over Winter) ensure that the batteries are fully charged
before storage. If necessary connect to a 9 to 24v power supply for
24 hrs prior to storage.
6.2 Fault Finding and Technical Support
6.2.1 Power Save Alarm sounds.
There has been no significant data activity on the network. The alarm
sounds to indicate that the instrument system will turn itself off. To
continue using the system press any button to cancel the alarm.
6.2.2 Lost Network Alarm sounds.
On a single instrumen t this indicate s that the particular instrument h as
lost communication with the Master*. Eithe r there is a problem with the
Master* instrument or the instrument in question has been moved out
of effective range.
On several instruments this indicates that these instruments have lost
communication with the Master*. Either there is a problem with the
master or the Master* has been moved out of effective range. The
instruments will power down shor tly after sounding the alarm to save
power.
6.2.3 A single instrument flashes the battery symbol and then
switches off.
The battery level is low on the particular instrument affected . Connect
to a 9 to 24V power source or leave in bright sunlight for 12 hours
minimum to recharge the instrument’ s inter nal battery . If the parti cular
instrument is the system Master* then the other instruments will sound
the Lost Network Alarm. To continue using the rest of the system
power down and restart the system from another instrument.
Maintenance and Fault Finding

6.2.4 Low Battery Alarm sounds.
The power level is low in the Hull Transmit ter, NMEA Inter face or Wind
Transmitter. On any Digital Instrument enter Setup and Calibration
mode (Page 18) and scroll through to the Health Chapter. Check the
signal levels of the Transmitters and Interface Box. The signal level
should show a value of greater than 3 to ensure correct operation.
Connect the Hull Transmitter or NMEA Interface to a 9 to 24V power
source for 12 hours minimum to recharge the internal battery. Leave
the Wind Transmitter in bright sunlight for 12 hours minimum to
recharge its internal battery.
6.2.5 Data is shown as dashes.
The information is not been transmitted to the instrument Displays.
There may be lost communication between the Wind Transmitter or
Hull Transmitter and the instrument Displays. On any Digital
instrument enter Setup and Calibration mode (page 18) and scroll
through to the Health Chapter. Check the signal l evels of the Hull and
Wind Transmitters. The signal level should show a value of greater than
3 to ensure correct operation.
6.2.6 Compass Transducer rattles and/or splashes.
Good! The fluxgate compass is gimballed in a fluid filled container to
ensure it is not affected by the boats movement in the water.
6.2.7 Compass information displayed on the instrument system does
not agree with the main steering compass.
Ensure that the main steerin g compass has been swung correctly and is
showing correct information. Ensure that the instrument system has
completed correctly the “Swing” procedure described on page 29. If
there are still differences, look for magnetic objects (loud speakers,
pumps and motors, etc.) close to the Transducer and try mounting the
compass transducer in an alternative location. After changing position
of nearby equipment or the Compass Transducer it wil l be necessary to
re-swing the compass following the procedure on page 29.
6.2.8 Boat Speed reads 0.
Information being transmitted from the Hull Transmitter is being
received with a Zero value. Check the paddle wheel for fouling, clean it
and make sure it turns easily.
6.2.9 Wind Speed reads 0.
Information being transmitted from the Wind Transmitter is being
received with a Zero value. If the anemometer cup s at the top of the
mast are turning and the Wind Speed reads 0 then there is a problem
with your Wind Transmitter.
6.2.11 The Depth Alarm does not sound.
If the actual water dep th is shal low and the alarm has not sounded it is
most likely that the alarm is switched off. From any Digital instrum ent
enter Setup and Calibration mode (page 18) and scroll through to the
Depth Chapter. Ensure the Depth Alarm settings are correct.

and battery status of the NMEA Interface. If the signal level shows a
value of greater than 3 then check the data connections and the
settings of the NMEA source equipment to ensure that NMEA 0183 is
being transmitted correctly.
* The “Master Instrument” is the instrument which was used to power up
the entire system. This instrument may be different each time the
system is used. If you are fault finding and are uncertain which
instrument is the master the switch off the system and swit ch on again.
