05.4 Safety requirements during use

� DANGER: Contraindications.
Do not use the Piezosurgery on patients with pacemakers or other implantable electronic devices.
This requirement also applies to the operator.
� DANGER: Breakage and wear of the inserts.
High frequency oscillations and wear may, on rare occasions, lead to breakage of an insert. If the
shape of an insert has been altered or if it is otherwise damaged, it is liable to break while it is
being used. Inserts in these conditions should not be used under any circumstances. In order
to avoid ingestion by the patient of a fragment of a broken insert, he/she should be instructed to
breathe through his/her nose during the treatment.
� DANGER: Control of infections.
For maximum safety of both the patient and the operator, clean, disinfect and sterilise the piezo-
electric handpiece, the inserts and the torque wrench after each treatment. Follow the appropriate
instructions for doing this provided in point 06.0 "CLEANING AND STERILISATION".
� WARNING: Contraindication.
Do not carry out treatments on metal or ceramic prosthetic artefacts. The ultrasonic vibrations could
cause decementing of such artefacts.
� WARNING: Contraindication.
After autoclave sterilising of the handpiece, wait for it to cool down completely before using it.
� WARNING: The electrical contacts inside the cord connector must be dry.
Before connecting the handpiece to the device, make sure that the electrical contacts of the
connector are perfectly dry, in particular after the autoclave sterilisation cycle. If necessary, dry the
contacts by blowing air onto them with the syringe
� WARNING: After using aggressive solutions, it is necessary to carry out a cleaning cycle of the
tubes and handpiece with distilled water, using the clean function (See point 06.1). If the tubes are
not cleaned, crystallisation of the salts could seriously damage the device.
� WARNING: To use the device correctly, it is necessary to press the footswitch and start it up
without letting the insert rest on the part to be treated. This will allow the electronic circuit to detect
the point where resonance of the insert is best without any interference, thus enabling optimum
performance.
If this is not done, contact with the part to be treated or with other surfaces before start-up could
cause tripping of the protection systems.
� WARNING: For spray treatment, use only inserts through which liquid is passed.

Service Centre
ERR1 Signal that the general protection system has been activated:
- Piezosurgery handpiece not connected to the device.
- Tuning circuit not working correctly.
- Handpiece failure.
ERR 2 Signal that the general protection system has been activated:
- Piezosurgery handpiece not connected to the device.
- Tuning circuit not working properly.
- Handpiece failure.
ERR 3 For the manufacturer only - Contact the Mectron Service Centre.
ERR 4 Signal that the general protection system has been activated:
- Tuning circuit not working properly.
- Handpiece failure.
ERR 5 Signal that the tuning scan has failed:
- Insert not correctly secured to the handpiece.
- Insert worn, broken or deformed.
- Electrical contacts of cord wet
ERR 6 Signal that the "power supply out of range" protection system has been tripped.
ERR 8 Signal indicating an error in communications with the scaler module.
ERR 9 Signal indicating an error in pump operation:
- Check whether the pump and tube are correctly installed.
- Check whether the pump is prevented from turning
ERR CKS Error signal. Firmware. Firmware checksum incorrect:
- If the equipment is working properly, call as soon as possible.
- If the equipment is not working correctly, stop using it and call the Mectron Service
Centre immediately.
