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.

Backlighting:  3 levels with daylight shutoff 
  System-wide or local control 
Power: Solar Powered 
  300 hrs autonomy by day, 7 nights at brightest 
  backlighting, 20 nights at economy backlighting 
 without charge 
Units of display:  Wind Speed 
  (knots, meters per second, Beaufort) 
Alarm:  Audible Alarm for Wind 
Weight: 285g (0.63lbs) 
Operating Temp.:  -100 to +600C (140 to 1400F) 
Frequency:  868 MHz or 905 MHz 
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. 
  Maintenance and Calibration 
 23 
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 fully recharge the instrument’s internal battery. If the 
particular 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. 
6.2.4 Low Battery Alarm Sounds. 
  The power level is low in the Hull Transmitter, NMEA Interface or Wind 
Transmitter. On any Digital Instrument enter setup and calibration 
mode (page 14) and scroll through to the Health Chapter. 
  Check the signal levels of the Transmitters and Interface Box. 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 14) and scroll through to the 
Health Chapter. Check the signal levels of the Hull and Wind 
Transmitters 
6.2.6 Wind speed reads 0. 
  Information being transmitted from the Wind Transmitter is being 
received with a Zero value. If the anemometer cups at the top of the 
mast are turning and the Wind Speed reads 0 then there is a problem 
with your Wind Transmitter. 
6.2.7 No NMEA data showing on external instruments. 
  From any Instrument enter setup and calibration mode (page 14) and 
scroll through to the Health Chapter. Check the signal level and battery 
status of the NMEA Interface Box. 
*  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 switch on again. 
The instrument which you switched on is now the master
