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.
