WARNING:
Please read this chapter thoroughly.
Villa Sistemi Medicali designs and builds its devices complying with the
related safety requirements; furthermore it supplies all information
necessary for a correct use and the warnings related to danger associated
with X-rays generating units.
Villa Sistemi Medicali, has not to be held responsible for:
•use of Rotograph EVO D different than the intended use,
•damages to the unit, to the operator, to the patient, caused both by
installation and maintenance procedures different than 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 authorized by Villa Sistemi Medicali.
Only the authorised personnel can remove the covers and/or have
access to the components under tension.

(!! /
This device has not been designed for use in environments where
vapours, anaesthetic mixes flammable with air, or oxygen and nitrous
oxide can be detected.
Avoid pouring water, even accidentally, or other liquids into the device,
as this could cause short-circuits.
Before cleaning the device, be sure that the 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 D has been built to support a continuous operation at
intermittent load; therefore please follow the described use cycles to
enable the device cooling down.
Rotograph EVO D 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 disconnected
from the main power supply before removing the covers.
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 picture below.

WARNING: PRECAUTIONS WHILE USING LASER CENTRING
DEVICES
Also if the laser devices, according to IEC60825-1, are in Class I:
•It is necessary to have 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 the 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 the highest care while mounting the column to 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 minutes.
• 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 minutes from the LED's switching off.
• The system construction does not allow the repair of
faulty/damaged parts, that must be replaced using original spare
parts supplied by Villa Sistemi Medicali. Only trained personnel
are authorized to make service interventions on the unit,
following the instructions contained in this manual.
WARNING:
The USB port on the keyboard MUST NOT be used with an external Hard
Disk with own mains connection. It has to be used only with USB Pen
Drives.

3 V d = 1.2 x
√ P
where "P" is the maximum output
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and "d" is the
recommended separation distance in
meters (m).
Field strength for fixed RF transmitter,
as determined by an electromagnetic
site survey, should be less than the
compliance level in each frequency
range.

Rotograph EVO D is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled.
The customer or the user of the Rotograph EVO D system can help
prevent electromagnetic interference by mantaining a minimum distance
between portable and mobile RF communication equipment (transmitter)
and the Rotograph EVO D as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at the maximum output power not listed above, the recommended
separation distance"d" in meters (m), can be estimeted the equation applicable to the
frequency of the transmitter, where "P" is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
Note:
(1) at 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
(2) these guidelines may not apply to all situations. Electromagnetic propagation is
affected by absorption and reflection of structures, objects and people.
