c) Cleaning the Multipurpose Sensor and the Outdoor Sensors
After a longer period of operation in the open, dust can deposit at the plastic surface of the
outdoor sensors. It can be removed rapidly with a cloth slightly moistened in water.
Never use a garden hose to clean the outdoor sensors, because they are only pro-
tected against rain coming from the sky above but not against jets of water coming
from the sides or below.
