dew or condensation may form on the lens in the 
CD player of the unit. Called lens fogging, this 
condensation on the lens may not allow CDs to play. 
In such a situation, remove the disc and wait for the 
condensation to evaporate. If the unit still does not 
operate normally after a while, consult your Kenwood 
dealer.
