10.7 Preventive maintenance
Surface cleaning – to keep the GN33 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.
Do not use any kind of strong solvents e.g. 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.
