4. Maintenance and proper care

4.1 Visual inspection

Inspect the system and particularly cables and connector assemblies regularly for signs of cracks, fis-

sures, and deterioration.

4.2 Cleaning

After every use the entire system should be cleaned.

ATTENTION!

Pay attention that no humidity could penetrate into the device during cleaning.

Do not use solvents (e.g. benzene, alcohol, etc.) for cleaning!

Remove loose dust with a soft brush. Clean the outside of components, if necessary, with an appropri-

ate clean cloth, only lightly moistened with clear water, and then rub it down thoroughly. If heavily

soiled, a few drops of rinsing agent may be added. Clean the connector pins with a commercial clean-

ing agent.
