[Elecraft] K2 near the sea: leave on or not?

[LAMB, Dick and Judy]

During the winter  I live about 200 meters from the Florida Atlantic 
beach.  Usually I have windows open, and although the salty sea breeze 
is pleasant,  it greatly speeds corrosion of metal.

Perhaps a maritime electronics expert could advise me as to whether I 
should leave my K2 (and other gear) on all the time, or power off when 
not it use.  I can speculate that the slightly increased temperature 
from leaving it on might prevent some condensation of moisture.  On the 
other hand, I recall from chemistry classes that increased temperature 
accelerates chemical reactions (like corrosion).  Are there any other 
reasonable precautions I can take?

Thanks
