gnetic compatibility (EMC)
This apparatus is in compliance with the applicable rule regarding EMC, Directive 89/336, that defines the
max. allowed emission levels from electronic devices and the required immunity from interference caused by
externally generated electromagnetic fields
It is not, however, possible to exclude radio signals coming from transmitters such as mobile phones or
similar mobile radio devices. These and other transmitting devices, including those in compliance with the
EMC standards, may influence the proper functioning of medical apparatus when used in proximity and with
a relatively high transmitting power. Therefore, the use of radio equipment proximity to electronically
controlled systems must be avoided in order to eliminate any interference risk.
Explanation:
The electronic apparatus that meets the EMC standards has been designed so that, under normal conditions,
any malfunctioning risk, caused by electromagnetic interferences, is avoided.
However, if radio signals coming from high frequency transmitters with a relatively high transmitting power are
used near the electronic apparatus, the risk of electromagnetic incompatibility cannot be completely
controlled.
Any transmissions by mobile radio equipment must be avoided.

taken.
During the use of x-rays, personnel present in the room must comply with the following rules concerning
protection against ionizing radiation:
• When necessary, use protective shielding against radiation in addition to the shielding already provided
on the unit.
• Use protective aprons containing a material equivalent to 0,35mm of lead. Material of this nature
reduces radiation at 50kV by 99,95% and at 100kV by 94,5%.
• The best protection against radiation is distance. It is therefore recommended that you stay as far as
possible from the x-ray source and the exposure target. For this purpose, use all of the cable length
provided for the foot-switch.
• Avoid walking or standing directly in the x-ray beam.
• Always use the smallest possible field of exposure by closing properly the collimator diaphragms. The
scatter dose produced depends principally on the volume of the irradiated object.

General disposal
Villa Sistemi Medicali produces radiological systems that are advanced in terms of safety and environmental
protection. Assuming that the unit is properly used, there is no risk to people or the environment.
In order to comply with applicable safety requirements, it is necessary to use materials that may be harmful to
the environment (for example: monobloc oil, protective lead, boards and electronic components). Therefore,
where necessary, proper disposal methods, according to the regulations of the country where the unit is
installed, should be followed.

Application & final destination
This unit is a portable x-ray system aimed to fulfil a wide range of clinical applications; it must be operated
exclusively by qualified, trained personnel who have been informed of the risks linked to the use of ionizing
radiation.
The compactness and maneuverability of the unit enables the operator to navigate through obstacles such as
doors, small rooms, narrow aisles and lifts with ease and allows accurate positioning between patient beds.
The ergonomic design of the unit allows the operator excellent visibility during operation and movement.
The perfectly balanced monobloc arm allows free movement and positioning even in the more awkward
positions. The shape of the base allows easy positioning and handling under the patient beds. The position
and shape of the four antistatic wheels make the system easy to move even on coarse surfaces.

Transport
For the transport of the unit, consider the following instructions:
• The unit must be OFF, the supply plug must be removed from the socket outlet and the cable
wound. (See Par. 4.6 “Shutdown procedure”).
• Place the monobloc - collimator group vertically and activate its rotation safety lock (see Figure 4).
• Pull the safety knob and rotate it till it is taken out (see Figure 5).
• Move downwards the arm by using the handles and by keeping in vertical position the monobloc-
collimator group; when the parking position is reached (see Figure 6) rotate and engage the safety
lock.
• Release the parking brake (see Figure 7 and Figure 8)
• Move the unit by using only the proper handles for the transport.
• Don't move the unit on surfaces with inclination higher than 10°.
• In order to overtake obstacles, it is possible to use the handle placed on the column.

• Turn the unit ON (see the paragraph “4.4 “Start up and checks at the ignition”)
• Turn the collimator lamp ON (the lamp will stay on for about 30secs).
• Collimate the x-ray beam to the dimension of the cassette (see the next paragraph)
• If necessary, release the brake to perform this operation (don't forget to set it again!).
• When the positioning has been completed, lock all the movements braking handles and the
parking brake.

1. Connect the unit to the mains. Voltage presence is indicated by the lightening ON of the yellow led
placed aside the ON button. If, while it is plugged, the red light is off, check that the automatic switch
lever, placed aside the unit, is up (ON position)
2. Turn the unit ON, pressing the ON button, follow step by step the Start up phase and verify its
performance by the following comparison:
• check of the display: every digit is completely ON (every pixel is dark);
• check of leds and beepers: all the leds of the keyboard turn ON and the beeper emits a
prolonged sound;

• Keep away as much as possible from the x-ray
source
• If on the display "READY" appears and the READY
led is ON, the exposure can be controlled.
• The emission control is made up of a two-steps
switch.
1°step: preparation (about 1 s)
2°step: exposure control
• It is possible to press the exposure control at once
(second step). Then there is a delay of about 1.2
s before the real exposure.
• Hold the x-ray control down till the exposure has
been performed properly (3 beeps).
Figure 14
The x-ray handswitch activates both the x-ray preparation phase “prep” and the emission phase “rad”. The
Figure 14 shows how to operate the handswitch to activate the preparation and the emission phases. It is not
possible to activate the emission phase “rad” without preparation; however, it is possible to perform
preparation without activating the emission.
The most frequent alarms during the use of the x-ray handswitch are the following:
1. TIME OUT – The x-ray handswitch has been pressed at the “1st step” (preparation) for more than 15s. In order
to perform radiography, it is necessary to release the handswitch and repeat the procedure.
2. MAN STOP RX – The x-ray handswitch has been released before the end of exposure. In this case, the display
will show the radiological data obtained. In order to repeat the exposure, it is necessary to press RESET.
