Notice
Do not rub, press, or touch any panels with solvents; caustic, corrosive, or abrasive
cleaning or disinfectant compounds; or other materials that could scratch the panels. Do
not use a betadine-based solution; it will cause discoloration.
Do not allow fluids to enter the chassis.
Do not clean the sterilizer case with abrasives. Product damage will result.
Product damage will result if you do not follow these notices when cleaning the
handpiece:
• Do not immerse the handpiece cable electrical connector in liquid.
• Do not use ultrasonic or automated cleaners.
• Do not use chlorinated substances such as bleach solution.
• Do not clean the handpiece with abrasives such as Ajax, Comet, or steel wool.
Product damage will result if you do not follow these notices when cleaning the Tip
Torquing Set.
• Do not use ultrasonic or automatic washers.
• Do not autoclave.
• Do not use chlorinated substances such as bleach solution.
• Do not clean with abrasives such as Ajax, Comet, or steel wool.
