Maintenance 

 

After a period of time, the rain sensor surface as well as the infrared sensor window will accumulate rubbish.

 

Use a piece of soft cotton wool and (maybe soapy) water to clean these surfaces. Let them dry. Do not rub strongly, specially not on the rain sensor surface.

 

NOTE

 

      Be careful not to scratch these surfaces.

 

      Do not leave fingerprints on the surfaces.
