Replacement Optical Sensor Cap ODOS-5005

The exchange of the sensor cap is performed very easily:
In case of the fish farming version, first remove the biting protection forwards. In
case of all other versions this step is not required. After that unscrew the old
sensor cap from the shaft by turning it to the left. Please, ensure that the optical
glass of the sensor does not get touched and get dirty. However, if this should
happen, clean the optical glass with a lint-free cloth (e.g. micro fibre cloth).
