Cleaning the unit
The unit is not protected against water spray.
Clean the unit only with an alcohol-based, commercially available (ethanol, isopropanol), colorless
disinfectant. The use of scouring powder or an abrasive sponge will damage its surface.
Do not submerge the unit in a disinfectant bath. It would be likely to be damaged.
Make sure the handpiece connection of the cord is dry
