6.2 Cleaning the Equipment
Dust or dirt can be removed from the equipment with a soft, dry cloth. Do not use chemical
cleaners to clean the equipment – they can remove paint and markings. Wipe the LCD carefully
to prevent scratching, using tissue paper and an LCD cleaner. To remove stubborn dirt, use an
LCD cleaner, wiping slowly with tissue paper so as to dissolve the dirt. Change paper frequently
so the dirt will not scratch the LCD.
