· Check the vibration outside the patient's oral cavity before use. If any abnormalities are found, stop using immediately and
contact dealer.
· Do not drop, hit, or subject to excessive shock to the Control Unit/Handpiece.
· To prevent possible tooth plane damage and handpiece overheating, Always use with sufficient water.
· Do not sterilize by ultraviolet light. Handpiece could discolor.
· Sterilize the Tip, Handpiece,Tip Holder, Tip Cover S and Tip Wrench by autoclaving. Wipe the Control Unit,Tip Holder, Tip,
AC Adaptor, Foot Control, and Handpiece Cord including the cover.

* Operation Principle
A sinusoidal electrical signal, at ultrasonic frequency ( f > 20kHz ) , is delivered by the generator. This signal is applied
to the 'piezoelectric ceramic' located inside the transducer. Piezoelectric ceramic converts this signal into mechanical
vibrations. These vibrations are at the same ultrasonic frequency as the electrical signal. The mechanical vibrations
are propagated towards the distal end of the transducer. The "TIP" insert, which is attached at the distal end of the
transducer, vibrates at ultrasonic frequencies and makes it possible to achieve the aimed purpose.
