Surface cleaning – to keep the CEXX cabinet and display screen clean, wipe
the surfaces with a clean damp cloth. For heavier cleaning, use a clean, damp
cloth which has been dipped in a solution of a mild dish detergent and water.
Wring out firmly before wiping the unit.
Never use cleaning solutions containing spirit, alcohol, gasoline or oils.
Electrical connections – periodically check the electrical connections. Make
sure that connections are tight and that no cables are frayed or worn.

sil using a scrubbing action.
Do not use a harsh abrasive or a solvent to clean the transducer.
