Cleaning

The cover disks in the transmitter and receiver must be cleaned regularly, depending on the amount
of dirt. Illumination of the „weak reception signal" message in the display of the receiver indicates
when cleaning is necessary at the latest.
For the cleaning of the Plexiglass cover disks, we recommend a mild detergent. The plexiglass
cover disks are highly resistant to dilute acids and alkalis, and against organic solvents to a limited
extent.
