9 Maintenance
General maintenance
The IS20 instruments are “repair by replacement” units,
and the operator is therefore required to perform only a
very limited amount of preventive maintenance.
If the unit requires any form of cleaning, use fresh water
and a mild soap solution (not a detergent). It is important
to avoid using chemical cleaners and hydrocarbons such
as diesel, petrol etc.
Make sure that all open SimNet connectors are fitted
with a protection cap (part no. 2400655).
Always put on the weather cover when the unit is not in
use.

Service item giving access to

about the different SimNet
messages used by the
