Cleaning
Outside Surface
The outside surface of the instrument, especially the cooling
fins, should be wiped free of dust and dirt when necessary.
Clean the RF input connector with a clean dry cloth. Use an
aerosol type non residue forming contact cleaner on the in-
accessible portions. Take special care to clean the metallic
contact surfaces and exposed face of the teflon insulator.
