9 Maintenance and care
The transmitter does not require any special maintenance or care.
However, we strongly recommend that you have the transmitter checked by an
authorised MULTIPLEX Service Centre at regular intervals (every two or three
years), depending on the intensity of use. Regular functional and range checks are
mandatory (see section 3.6 "Range check" on page 47).
Never use abrasive cleaning agents such as spirit or solvents!
Remove dust and dirt preferably with a soft bristle brush.
Remove persistent dirt, in particular grease and oil, with a moist cloth and,
if required, with a mild household cleaning agent.
Protect the transmitter against mechanical impact and shock.
The transmitter should be stored and transported in a suitable container (bag
or carrying case).
At regular intervals, check that the transmitter case, mechanical parts and
especially the wiring and contacts are in good condition.
