Radiazioni Ionizzanti superiori alle dosi massime ammissibili (art. 95 DPR 185/64).
3) Assicurare la sorveglianza fisica della protezione a mezzo di un E.Q. che ha il compito di
effettuare la delimitazione della zona controllata con l’applicazione dei relativi contrassegni;
l’esame preventivo e periodico del progetto d’impianto; il controllo periodico dell’efficacia dei
dispositivi tecnici di radioprotezione; la valutazione periodica delle esposizioni e delle dosi
individuali assorbite dagli eventuali lavoratori e il rilascio del benestare radioprotezionistico
che dovrà essere rinnovato con periodicità annuale (art. 70 e 72 DPR 185/64).
4) Pagare la Tassa Regionale annuale a mezzo C/C. intestato alla Tesoreria della Regione.

IONISING RADIATIONS
X-rays are harmful, if improperly used. Therefore, the instructions contained herein must be strictly
observed.
ARDET Dental & Medical Devices s.r.l. produces x-ray equipments which conform with the most
restrictive worldwide rules of radio protection in force.
Aim of an x-ray equipment is the emission of x-rays for medical diagnosis by means of a film or an
“Imaging” system.
In any case, independently from the safety of our equipments, we suggest you to protect yourself
and your patient from the spread radiations (secondary radiations).
GENERAL PROTECTION AGAINST X-RAYS
a) Control x-ray emission at a distance of at least 2 meters from the focal spot and the x-ray beam.
b) Reduce, as most as possible, the radiation level to which the patients and operating personnel
are exposed.
c) During x-ray emissions, only the operating personnel and the patient must be present.
d) In case it should be necessary to help patient to hold the film in position, the operating personnel
must use appropriate tools and wear anti radiation gloves and apron to protect hands and body.
In any case, the patient must always be protected with a lead apron 0,25 mm. min.
Operations which produce x-ray emission are preceded by symbol “Ionizing Radiation” as to
remember all the conditions to observe in compliance with the rules in force in your Country.
AMBIENT AND USE CONDITIONS
The room where the x-ray equipment is to be used should satisfy the following conditions:
1) Temperature between 10 and 40° C.
2) Relative humidity from 30 to 75%
3) Atmospheric pressure from 700 to 1060 hPa.
4) The electrical wiring must conform with CEI 64-8 (the regulations concerning the electrical
wiring to be used in surgery)

Pag. 8
OPERATING INSTRUCTIONS
ORIX 70
5) Concerning the protection against radiation, the room must conform with the regulations in
force in the country where the equipment is used.
6) Before leaving the surgery, turn the main switch to the OFF position.
CAUTION!
7) The equipment is not liquid-proof (traditional equipment)
8) The equipment is not suitable for use in presence of flammable anesthetic gas based on oxygen
and nitrogen protoxide
9) If an electric bistoury or other electrical equipments which do not conform with CEI EN
60601-1-2 specifications are used in surgeries or nearby, interferences or disturbances may
arise thus causing the x-ray equipment to malfunction. In this case, disconnect the x-ray
equipment before using any other instruments or device.
10) The ORIX-70 x-ray generator contains mineral oil, which is classified as a special by-product.
Therefore, when the generator is to be put out of service it should be sent back to the
manufacturer or given to a company authorized to dispose of mineral oil and the special by-
products.

CAUTION!
The SELEMATIC x-ray control is programmed by default on D film sensitivity which corresponds

is activated (green light - ref. n.7) the following data, memorised by the microprocessor, are
displayed on the symbols relative to patient and tooth
Changing the sensitivity of the film with the relative key (ref. n.3) the exposure time is
automatically modified whilst the other two technical factors relative to the size of the patient (red.
n. 10) and the tooth (ref. n. 12) remain the same. The exposure time values displayed are as follows:

a) Select the work station pushing the relative key (ref. n.8)
b) Select the type of tooth (ref. n. 6 for mandibular arcade and ref. n. 12 for maxillary arcade) using
the left and right arrows (ref. n. 5)
c) Select the type of patient (large/medium/small) using the left and right arrows (ref. n.4)
d) Press “ENTER” (ref. n. 2), automatically the LED of all the selected technical data
(patient/tooth/generator) will start to blink. This means that the microprocessor has confirmed
the chosen factors and therefore the x-ray control is ready to activate the x-ray generator.
e) press the x-ray key (ref. n. 14) and keep it pressed for the whole count-down time until the
display reaches zero. During this phase, the x-ray LED will lighten (ref. n.9) and a BEEPER will
give an acoustic warning for the whole time of radiation.
f) At the end of the exposure time (zero setting of the display and stop of the BEEPER) the x-ray
control goes into sleeping mode (pause) and will remain inoperative for a minimum time which
is 30 times the exposure time previously executed.
Example:
Exposure time 0.4 seconds
Pause time 12 seconds

Pag. 20
OPERATING INSTRUCTIONS
ORIX 70
The inactivity time is shown by the blinking of all the leds on the control panel. At the end of the
pause time, the microprocessor will reset the parameters of the last exposure which may be
maintained or modified according to the new x-ray which have to be taken.
CAUTION !
A the end of the duty cycle, all the technical data regarding the last x-ray remain selected
(generator/patient/tooth).
CAUTION !
In case that after an exposure the x-ray control is intentionally or accidentally disconnected by
means of the main switch (ref. n.1), on its re-start the memory of the microprocessor will reset the
default technical parameters.
CAUTION !
g) The accidental release of the 'DEAD MAN' key (ref. n. 14) during an exposure, immediately
arrest the x-ray control timer, automatically stopping the x-ray emission and on the display (ref.
n.7) the following error codes are displayed:
E01 when for the almost immediate release of the x-ray key the exposure time is equal or less
than the minimum time requested by the filament of the x-ray tube to reach its temperature
of emission.In this case no significant radiation has been emitted and therefore the x-ray will have
to be repeated. To reset the functions press “ENTER”.
E02 when releasing of the x-ray key the exposure time has been partially completed and, in any case, it
has exceeded the minimum time requested by the filament of the x-ray tube to reach its temperature
of emission. In this case a sufficient radiation has been emitted. Before taking a new x-ray develop
the x-ray already made in order to verify its quality. To re-start the x-ray control repeat the procedure
showed for error E01.
h) In compliance with the relative standards, linearity and repeatability are guaranteed from a
minimum time of 0,03 seconds (with manual adjustment) to a maximum time of 1,32 seconds
(with manual adjustment) if all the technical factors are correctly set.
