  1. The poor hydrophobicity of window glass leads to a drop in CNR to -20dB when there is water on the window, necessitating window replacement.
  2. The white LED light is damaged; the power switch can supply power normally, but the indicator light does not light up, requiring replacement.
  3. There is no waterproof device on the front door, and one needs to be installed.
