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

6.2.1Power 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.

6.2.2Lost Network Alarm sounds.

On a single instrument this indicates that the particular instrument has lost communication with the Master*. Either 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 shortly after sounding the alarm to save power.

6.2.3A 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 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.
