8 Maintenance and Fault Finding
8.1 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 displays are to be stored for a long period (e.g. over winter) ensure
that the batteries are fully charged before storage. If necessary connect
to a 9 to 30V DC power supply for 24 hrs prior to storage.
8.2 Fault Finding and Technical Support
My Dual Maxi Display does not start when I switch on the system
Check that you have correctly carried out auto-networking to connect your
Dual Maxi Display to the network. See the yellow Auto Networking sheet.
My Remote Display does not go into Remote Control mode
a) Remote control mode is not available for 30 seconds after the system
is switched on. Wait 30 seconds and try again.
b) Remote control was not supported on displays manufactured before
2006. Ensure that you switch on the system using a display
manufactured after 2006, the Remote Display or a Dual Maxi Display.

Power No Volts alarm sounds
The Hull Transmitter and Wireless (NMEA) Interface must be connected
to external power supplies. If this connection is not made, then you will
see this alarm 10 seconds after powering up your system. Any DC
voltage between 9 and 30V is sufficient to power the Hull Transmitter and
Wireless (NMEA) Interface.
