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.
