05.4 Safety Requirements during use
�
DANGER: Contraindications.
Do not use the scaler on patients fitted with pace-makers or other implantable electronic devices.
This warning also applies to the operator.
�
DANGER: Contraindications.
Do not carry out scaling treatments without a water spray as this could cause overheating of the
insert with consequent injury of the tooth. The only treatments that can be carried out without a
water spray are those for which the “Dry Work” inserts, which are not cannulated, are designed.
Ask for a catalogue of Mectron inserts.
�
DANGER: Breakage and wear of the inserts.
In rare cases the high-frequency oscillations and wear can lead to breakage of an insert. Inserts of
which the shape has been altered or that are damaged in any way are liable to break during use.
Any such inserts should not be used under any circumstances. In order to avoid ingestion of a
fragment of a broken insert, the patient should be instructed to breathe through his nose during the
treatment.
�
DANGER: Infection control.
To ensure maximum safety of both the patient and the operator, clean, disinfect and sterilize the
piezoelectric handpiece, the inserts and torque wrench after each treatment. Follow the instructions
on this subject container in Section 06.0 “CLEANING, DISINFECTION AND STERILISATION”.
�
WARNING: Contraindication.
Do not carry out treatment for removing calculus on metal or ceramic prosthetic artefacts as the
ultrasound vibrations could cause decementation of the artefacts.
�
WARNING: Contraindication.
Wait for the handpiece to cool down completely before using it again after it has been autoclave
sterilised.
�
WARNING: The electric contacts inside the handpiece and cord connectors must be dry.
Before connecting the handpiece to the cord make sure that the electric contacts of both connec-
tors are perfectly dry. This is a particularly important check after an 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
tube and of the handpiece with distilled water, using the Clean function (See point 06.1). If this is
not done, the salts may crystallise and seriously damage the device.
�
WARNING:
Use cannulated inserts only to carry out treatments requiring a spray.
�
WARNING:
For a correct use of the device it is necessary to press the pedal and start the
device without placing the insert on the part to be treated. This will enable the electronic circuit to
recognise the best point of resonance of the insert without interferences, so as to achieve optimum
performance. Contact with the part to be treated or with other surfaces before starting the device
could cause the tripping of the safety circuits.
05.5 Safety and alarm circuits
The device has a diagnostic circuit enabling tripping of the safety and alarm systems to be
recognised. They are signalled on the display.
WARNING 1
General safety circuit tripped:
- Scaler handpiece not connected to the device;
- Improper functioning of the tuning circuit;
- Handpiece failure.
WARNING 2
General safety circuit tripped:
- Scaler handpiece not connected to the device;
- Improper functioning of the tuning circuit;
- Handpiece failure.
WARNING 4
General safety circuit tripped:
- Improper functioning of the tuning circuit;
- Handpiece failure.
WARNING 5
Tuning scan failed:
- Insert not properly tightened onto the handpiece;
- Insert worn, broken or deformed;
- The electric contacts of the cord and/or of the handpiece are wet;
- Overheating of handipece.
WARNING 6
Power supply voltage out of range.
WARNING 16
Error in communications with the scaler module:
- The device switches off. Contact the Mectron Service Centre immediately.
WARNING 17
Pump operational error:
- Check that the pump and the tube are properly installed;
- Make sure that there is nothing preventing the pump from turning.
WARNING 18
Pump operational error:
- Contact the Mectron Service Centre.
WARNING 19
Scaler module initialisation error:
- The device switches off. Contact the Mectron Service Centre immediately.
WARNING 21
Checksum error, modification of scaler module firmware:
- The device is working properly. Contact the Mectron Sertice Centre as soon as
possible;
- The device is not working properly. Contact the Mectron Service Centre
immediately and in the meantime do not use the device.
WARNING 22
Checksum error, modification of mainboard firmware:
- The device is working properly. Contact the Mectron Sertice Centre as soon as
possible;
- The device is not working properly. Contact the Mectron Service Centre
immediately and in the meantime do not use the device.
WARNING 26
Voltage low safety circuit tripped:
- The device switches off. Disconnect the power supply unit from the power outlet
and contact the Mectron Service Centre immediately.
WARNING 27
Voltage high safety circuit tripped:
- The device switches off. Disconnect the power supply unit from the power outlet
and contact the Mectron Service Centre immediately.
