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
6.2.1 Power 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.
6.2.2 Lost 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.
6.2.3 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 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.
