4.1 Maintenance
The system requires a maintenance check at regular intervals. Here, it should be checked whether the optics
of the camera are clean, correctly focused and whether the shutter systems still function properly. This
includes a complete opening and closing of the shutters. These points must be observed, as they have a
direct influence on the temperature measurement.

Never use cleaning compounds which contain solvents (neither for the lens nor for the housing).
The lens surface can be cleaned with a soft, humid tissue (moistened with water) or a lens
cleaner (e.g. Purosol or B+W Lens Cleaner).
