The surface of the Control Unit may feel warm after prolonged use. Turn the Power/Volume Knob to OFF
•
and cool the device.
Users are responsible for operational control, maintenance and inspection.
•
Clean/sterilize the product immediately after using it. Then store it. Leaving it non-sterile might lead to failure.

to use coolant water.
* 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.
