grant an adequate reference in performing diagnostics and repair
operations normally carried out by the service engineer.
The manual may not reflect changes to the product not impacting service
operations.
Rotograph EVO, produced by VILLA SISTEMI MEDICALI S.p.A., is an
X-ray device for the radiographic analysis of the maxillo-facial complex.
The basic version of the Rotograph EVO performs Panoramic, Sinus and
TMJ examinations of the maxillo-facial complex.
The following options are available and must be ordered separately:
• EVO XP (Extended Projection Package); it allow the execution of the
following examinations: Emi-panoramic, Reduced dose Panoramic,
Frontal dentition, Improved orthogonality Panoramic
• CEPH; it allows the execution of the following examinations:
- CEPH exam in different formats
- CARPUS exam.
This manual provides to the technical personnel the instructions for
proper and safe installation and maintenance of the appliance.
The device must be used complying with the procedures described and
never be used for purposes different from those herewith indicated.
ROTOGRAPH EVO is an electro-medical device and it can be used only
under the supervision of a physician or of highly qualified personnel,
with the necessary knowledge on X-ray protection.
The user is liable as concerns legal fulfilment related to the installation
and the operation of the device.

2. SAFETY INFORMATION
WARNING:
Please read this chapter thoroughly.
Villa Sistemi Medicali designs and builds its devices in compliance with
the safety requirements; furthermore it supplies all information
necessary for correct use, and the warnings related to danger associated
with X-ray generating units.
Villa Sistemi Medicali cannot be held responsible for:
• the use of Rotograph EVO different from the intended use
• damage to the unit, to the operator, to the patient, caused both by
installation and maintenance procedures different from those
described in this Manual and/or by wrong operations
• mechanical and/or electrical modifications performed during and
after the installation, different than those described in this Manual.
Installation and any technical intervention must only be performed
by qualified technicians authorised by Villa Sistemi Medicali.
Only authorised personnel can remove the covers and/or have
access to the components under tension.

Safety information
Rotograph EVO (Rev. 1)

2.1. Warnings
This device has not been designed to be used in environments where
vapours, anaesthetic mixtures flammable with air, or oxygen and nitrous
oxide, can be detected.
Do not let water, or other liquids, into the device, as this could cause
short-circuits and corrosion.
Before cleaning the device, be sure the that main power supply has been
disconnected from the equipment. Pushing the ON/OFF button on the
basement of the equipment, it mustn't switch on.
Wherever necessary, instruct the customer regarding the following:
• to use the proper accessories, such as the leaded aprons, to protect
the patient from radiations
• while performing the radiography, no one, apart from the operator
and the patient, must remain in the room
• to clean and disinfect, when necessary, all parts that can be in
contact with the patient
• to replace the bite or the bite protective sleeve and the ear-
centring devices after the use.
Rotograph EVO has been built to support a continuous operation at
intermittent load; therefore please follow the described use cycles to
enable the device to cool down.
Rotograph EVO must be switched off while using devices such as
electrical lancets or the like.
Never try to rotate the moving arm manually when the unit is
switched on, to avoid permanent damage to the unit.
Movement is only possible in case of Error 362 because motors are
disabled to permit the patient exit.
The authorised technician must be sure that the unit is disconnect from
the main power supply before removing the coverings.
The high frequency generator, located on the rotating arm, can hold
dangerous voltage for more than 2 minutes from the power off.
Though the X-ray quantity supplied by dental X-ray units is quite low
and distributed on a small surface, the operator must adopt the
precautions and/or fit protections for the patient and himself, during the
execution of a radiography. It is advisable to control the X-ray emission
from a protected area, by means of a remote control. In case it is
necessary to operate near the patient, please stay as far as the cable of
the remote control allows it, or at least 1,5 m (4.92') both from the X-ray
source and from the patient, as shown in the pictures below.

WARNING: PRECAUTIONS WHILE USING LASER CENTRING
DEVICES
Also if the laser devices, according to IEC 60825-1, are in Class I:
• It is necessary an adequate illumination in the room.
• Do not look into the output windows of laser centring units.
• Do not stare at the reflections of laser pointers.
• Instruct the patient to keep his/her eyes closed as long as the laser
pointers are active.
• Before starting an examination, the patient must remove earrings,
glasses, necklaces and whatever else could reflect the laser beam or
be impressed on the radiographic image.
• Do not clean the openings of laser centring devices with tools that
could modify the optics. Necessary cleaning must be performed only
by authorised technicians. Operations different than those indicated
could cause the ejection of dangerous non-ionising radiations.
WARNING: PRECAUTIONS DURING INSTALLATION AND SERVICE
INTERVENTIONS
• Please take highest care while mounting the column at the wall and
strictly follow the instructions listed in this manual.
• Before removing the covers of the column, or before removing the
covers of the Generator board (A10), disconnect the power supply to
the device, both switching the main switch and the magneto-thermal
differential off, and wait at least 2 minute.
• When the device is supplied without the above mentioned coverings,
pay the highest attention since high voltage is generated in the
supply unit, and the voltage is at about 400 Vdc on the Generator
board. This is indicated by the green LED H1. Should the LED be off
and before any other intervention, disconnect the device from the net,
wait at least 2 minute, then check the fuses F1 (10AF) in the supply
unit, or F2 (5AF) on the Generator board (see circuit diagram).
• Each intervention must be performed after having disconnected the
device from the supply net and after LED H1 is OFF. It is anyway
advisable to wait at least 2 minute from the LED's switching off.
• The system construction do not allow the repair of
faulty/damaged parts, that must be replaced using original spare
parts supplied by Villa Sistemi Medicali. Only trained personnel
is authorized to make service interventions on the unit,
following the instructions contained in this manual.
