Initial stage of the dew sensor cleaning procedure has been sent via DIRECT e-mail, this followed if necessary with the full disabling info, although the undermentioned advice should always be observed.
---------------------------------------------------------------------------- -            - AN IMPORTANT POINT CONCERNING THE MODIFICATION -
The instructions given 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!!
