Function
Note: The PACER function will provide more thorough cleaning than
the AUTO function because it first develops a thick dew/frost
layer into which soluble contaminants dissolve. When heated,
some of the contaminants are flash evaporated and the
remaining residue accumulates in clusters, resulting in the
cleaning of much of the mirror's surface. The PACER cycle
generally takes longer to complete.
