Notes on cleaning
- Wipe off any dirt gently with a soft cloth. If the unit is very dirty, soak a soft cloth in neutral detergent diluted with water, wring it out hard, wipe off the stain, and then wipe dry with a dry cloth. Do not use alcohol, benzene, thinner, etc.
- Strongly wiping off the unit using a cloth with dust may scratch the surface of the unit.
