1.4 SafetyPrecautions
WARNING: Contraindications.
Do not use the device on patients who
carryheartstimulators(Pace-makers)or
other implantable electronic devices. This
precaution also applies to the operator.
WARNING: Contraindications. Do not
perform scaling treatments without water
spray in order to avoid the insert tip over-
heating which may cause damages to the
tooth. Treatments with no water spray can be
carried out only with “Dry Work” insert tips
which do not have the water passage.
CAUTION: Contraindications.
Ultrasonicscaler. Do not perform treatments
on prosthetic artifacts made of metal or
ceramics. The ultrasonic vibrations could lead
to the de-cementing of the artifacts.
WARNING: Contraindications.
Interferencefromotherequipment.
An electrical scalpel or other electro-surgical
units near the compact piezo LED device may
interfere with its correct operation.
WARNING: Contraindications.
Interferencewithotherequipment.
ThoughcomplianttothestandardIEC60601-
1-2, compact piezo LED may nonetheless
interfere with other devices nearby.
compact piezo LED must not be used near
to or stacked on other devices. However,
if this were to prove necessary, check and
monitor correct operation of the device in
thatconguration.
WARNING: Riskofexplosion. The
device cannot operate in environments where
theatmosphereissaturatedwithammable
gases(anestheticmixtures,oxygen,etc..).
CAUTION: In case the end user, when
operating in his or her own medical study
or clinic, must subject the electro-medical
equipment and systems to periodical
inspections in order to adhere to imposed
requirements, the test procedures that must
be applied to electro-medical equipment
and systems to evaluate safety must be
performedinlinewiththestandardEN62353
‘Medical electrical equipment - Periodic
inspections and tests to be carried out after
repairofmedicalelectricalequipment’.The
frequency of periodic inspections in the
intended conditions of use described is
once per year or every 2000 hours of use,
whicheverconditionissatisedrst.
WARNING: Checkingdevicestatus
beforethetreatment. Before every
treatment, always check that the device
works perfectly and that the accessories are
ecient.Incaseofoperatingabnormalities,
DO NOT perform the treatment. Contact an
Authorized Piezosurgery Inc. Service Center if
the abnormalities concern the device.
WARNING: Cleaningandsterilising
neworrepairedinstruments. All the new
or repaired device accessories are not sterile.
Atrstuseandaftereachtreatmentthey
must be cleaned and sterilized by carefully
following the instructions in Chapter6on
page 17 of the Use and Maintenance
Manual.
WARNING: Diamond coated insert tips
are SINGLEUSEONLY. The diamond coated
insert tips are intended to be used on an
individual patient during a single treatment
procedure and then disposed of. The
diamond coated insert tips must be sterilized
onlyonetime,priortherstuse.

COMPACT PIEZO LED
WARNING: Infectionscontrol.
To ensure maximum safety of the patient and
the operator, before using all the reusable
parts and accessories, make sure you have
rstcleanedandsterilizedthem,following
the instructions of the Chapter6onpage
17 of the Use and Maintenance Manual.
CAUTION: Contraindications. Allow
reusable, autoclavable items (the handpiece,
the insert tips, the torque wrench, and any
otheraccessorythatcanbesterilized)to
gradually return to room temperature after
steam sterilization and prior to usage. The
cooling process must not be accelerated.
WARNING: Breakageandwear-outof
the insert tips. High frequency oscillations
and wear-out may, in rare circumstances, lead
to the breakage of the insert tip.
Deformed or otherwise damaged insert tips
are susceptible to breakage during their use.
These insert tips must never be used.
If an insert tip breaks, check that none of its
fragments remain in the treated part and,
atthesametime,applyeectivesuctionto
remove them.
The patient must be instructed to breathe
through his nose during the treatment, or
a dental dam must be used to prevent the
patient from ingesting fragments of broken
insert tips.
Check the level of wear of the insert tip and
its integrity before and during each use. If
there is a decrease in performance, replace
it. The level of wear of the most common
inserttips(S1,S1-S,S2,S5,P2,P4,P10)can
be checked by using the INSERT TIP - CARD
supplied. To use the INSERT TIP - CARD
correctly:
• Position the insert tip on the INSERT
TIP-CARDsothattheprolematches
theoneprintedonthecard.Theprole
printed on the card has a red line
indicating the wear limit;
• If the insert tip has a length less than
the wear limit, its performance will be
signicantlylowerthanthecondition
of a new one and replacement is
recommended.
If the layer of titanium nitride (golden
surface),wherepresent,isvisiblyworn,the
insert tip must be replaced. The use of a worn
inserttipdecreasesitseciency.
When the nitride coating wears out, the
cuttingeciencydecreases;re-sharpening
the insert tip damages it and is therefore
forbidden. Check that the insert tip is not
worn out.
During the intervention, frequently check that
the insert tip is intact, especially in its apical
part.
During the intervention, avoid prolonged
contact with retractors or with metallic
instrumentation in use. Do not exert excessive
pressure on the insert tips during their use.
WARNING: OnlyuseoriginalMECTRON
inserttips,accessories,andspareparts.
CAUTION:Nomodicationofthis
equipment is allowed.
WARNING: Prior to any use, system
components must be inspected for damage.
Do not use if damage is apparent.
WARNING: Do not operate the device if
handpiece is defective, damaged or broken.
Immediately replace the handpiece.
NOTE: In case of accident attributable to the
device during correct use and in accordance
with the intended use, a report must be
made to the Competent Authority and
manufacturer indicated on the product label.

62353‘Electro-medicaldevices-Periodical
inspections and tests to be performed after
repair interventions on electro-medical
devices’.Theintervalforperiodicchecks,in
the intended operating conditions is one year
or 2000 hours of use, depending on which of
thesetwoconditionsoccursrst.
WARNING: Riskofexplosion.
The device cannot operate in environments
where there are saturated atmospheres of
ammablegases(aestheticmixtures,oxygen,
etc.).
CAUTION: Theelectricalcontactsinside
thecordandhandpiececonnectorsmust
be dry. Before connecting the handpiece to
its cord, check that the electrical contacts are
perfectly dry, on both parts. If necessary dry
them with compressed air.
WARNING:OnlyuseoriginalMectron
inserttips,accessories,andspareparts.
CAUTION: It is prohibited to make any
changes to the device.
4.2 MechanicalInstallation
Figure2apagina12 shows the dimensions of the module.
The module can be secured to the dental unit by means of two M3 threaded holes (Ref. A and
B),oralternatively,bymeansoftwoholeswithdiameter2mm(Ref.CandD).
WARNING: The M3 screw used to secure
the module must not penetrate the inside of
said module for more than 4mm as it may
damage the circuits.
The holes with diameter 2 mm have a
maximumdepthof6mm.
The module is also supplied with holes on the
sides, but these must NOT be used to secure
it. The holes on the sides are used to attach
several internal components.

INSTALLATION
4.3 ElectricalConnections
compact piezo LED allows various electrical
congurationstosatisfythecharacteristicsof
the dental unit in which it is housed.
The dental units to which the
compact piezo LED device can be connected
must be able to provide one of the following
power supplies:
• 24V~50/60Hzor
• 32 V
with minimum power 40VA.
Moreover, it must have a 2A, 250V safety fuse.
Fortheelectricalconnections,the
compact piezo LED device is equipped with 2
connectors (see Figure3apagina13 ):
• M1 : connector with 2x8 contacts for the
module controls;
• M2 : connector with 2 contacts for
connection of the handpiece cable
(piezoelectricelementscontrol);
• M3 : connector with 2 contacts for
connection of the handpiece cable (LED
control).
