1.3 Maintenance
The device is maintenance-free.
1.4 Cleaning
The case and the TFT display should be cleaned with a soft, lint-free dust cloth. Never use solvents such as diluents for
cellulose lacquers, acetone or similar since they may damage plastic parts or the coating on the front panel.
Any dust should be removed from the ventilation slots regularly so that the air circulation provided by the built-in
ventilator is not obstructed.
1.5 Calibration
The device should be recalibrated at least every two years. It is automatically calibrated at the factory in case of
upgrading, repairs or servicing.
1.6 Service
Service address: see back cover of operating manual.
