- Care and Cleaning
Your SAS-300 is made to withstand marine elements but a little care ensures a trouble free life.
Accumulations of salt and sand, if not removed, will eventually mar the finish. No solvents or harsh
cleaners should be used. The display unit may be wiped down with a damp cloth while avoiding the
display window. Be careful not to scratch the display window surface. Gently remove any sand or other
grit particles before cleaning the display window. The display window should be cleaned only with
wateaqs0r and a clean soft cloth using very light pressure.
