Dew sensor cleaning info sent via DIRECT e-mail. This can only be taken as a first stage of curing the problem as if it continues then disabling the sensor is the only option remaining, info on the procedure sent if requested. IMPORTANT - Further info on sensor disabling, should this be required! Instructions provided are really aimed at technically minded people of a "practical" nature who are acquaint at working on smaller electro-mechanical devices of a precision nature, or who have a flair for this sort of thing, and so in the interests of not making the situation any worse I would strongly advise anyone who does not really come into that category NOT to attempt this work, as it involves separating the case and the unscrewing the main circuit board to gain access to the board below it, this requiring the disconnection of ribbon cables etc, it is also necessary to carry out the precision soldering of two "very" narrowly spaced PCB pins, so the possession of a fine tipped soldering iron is also absolutely essential! So taking the above into consideration the qualification mentioned is really a MUST!! It should be emphasised that there are NO shortcuts into getting over this problem other than what's been aforementioned, and even if the memory reset does affect a cure it can only be adopted as a stop gap measure as the CPU could lock up again at some point in time, and unfortunately in many instances does!!
