Maintenance
The IS70/IS80 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.
If a weather cover is available this should be put on
when the unit is not in use.
