Warnings
The system has not been designed to be used in presence of vapours,
anaesthetic mixtures that are flammable with air, or oxigen or nitrous
oxide.
Ensure that water or other liquids do not get into the machine so as to
prevent short-circuits and corrosion.
Always disconnect from mains before cleaning the machine.
Where necessary, accessories such as lead-sealed aprons must be used
to protect the patient from radiations.
Only the patient and the operator may remain in the room during the
execution of the radiography examination.
ROTOGRAPH-D has been developed for continuous use with intermittent
load. The prescribed operating cycles to allow the heat accumulated by
the radiogenic source to be discharged must be observed.
Although the appliance has been designed to have a reasonable degree of
protection from electromagnetic interference, it must be installed at a
certain distance from electricity transformer rooms, static continuity
unit, portable two-way hand radios and cellular phones. The latter may
only be used at a distance of over 1.5 meters from all elements of the
machine.
All instruments or equipment for professional use and used near the
machine must be in conformance to the electromagnetic compatibility
standards.
Nonconforming instruments whose low immunity to electromagnetic
fields is known must be installed at least 3 meters away from the
ROTOGRAPH-D and be powered via an independent electric line.
ROTOGRAPH-D must be switched off during the entire period of use of
ESU (Electro Surgery Units) units or similar equipment.
Clean or eventually disinfect the chin support, positioning handles,
temples clamp support and any other part that may come in touch with
the patient.
At the end of the examination, replace the bite.

Although the X-ray dosage supplied by dental radiology appliances is on
average low and distributed over a relatively small surface, the operator
must take the necessary precautions and/or follow the safety procedures
for both himself and the patient during an exposure. We recommend
that the X-ray activation always be commanded from an X-ray protected
area via remote control. If it is necessary to operate the exposure near
the patient, remain at the maximum distance allowed by the remote
control cable in the direction opposite to the emission of the rays, at a
distance of at least 78 ¾ inches (2 meters) from both the radiation
source and patient.

Environmental risk and disposalEnvironmental risk and disposal
Environmental risk and disposal
A number of machine parts contain materials and liquids that upon
completion of the machine’s life cycle must be disposed of at recovery
centers established by the local health units.
The machine contains the following materials and/or components:
•Tubehead: dielectric oil, lead, copper, iron, aluminum, glass,
tungsten, beryllium
•Control box and remote control: iron, copper, glass resin, non-
biodegradable plastic casings
•Column, rotating arm, exten ion : iron, lead, aluminum, copper,
non-biodegradable plastic materials, glass resin.
WARNING:
Before disassembling the parts, lock the counterweight of the slider
inserted in the column. This is possible only after having slid the slider
all the way down and inserted a pin approximately 25cm in length and
8mm in diameter. Once the pin has been inserted, move the slider
towards the top until the counterweight rests on the pin. Remove the
tubehead and some of the parts of the rotating arm. Holding the slider
firmly, remove the pin and move the slider towards the top to the
metallic stop of the column. At this point, remove all the remaining
parts.

3.2 Description
DescriptionDescription
Description
ROTOGRAPH-D has been designed to perform the following
examinations:
•Panoramic examination
•"SINUS" examination of the paranasal sinus
•Examination of the Temporo-Mandibular Joints (TMJ) with open or
closed mouth on a single image
All the allowed examination may be made with different parameters
according to the setting of the remote-control (please refer to Chapter 6
of User’s Manual).
ROTOGRAPH-D is controlled by a soft touch console and equipped with
an alphanumeric digital display for a clear indication of the working
parameters and operative messages.
The operative cycle is entirely run by a microprocessor, controlling its
different modes: from programming of the emission parameters
according to the chosen examination and the patient's size, to the
voltage fluctuation and to the notification of possible anomalies, failures
or errors.
The excellent quality radiographs thus obtained is the result of a clever
design based upon the pseudo-elliptic rotation system, the original light
beam-luminous cross pattern centering system, the use of green emiting
Rare Earth Intensifying screens and most of all the small dimension of
the focal spot.
This particular rotation system allows an orthogonal imaging of all teeth
and wide image layer with an optimum focused zone of 10 mm for the
incisors and 20 mm for the molars.
ROTOGRAPH-D, besides operating in the programmed mode, can also
operate in the manual personalized mode by modification of the
parameters, as described in chapter 5.
In the Panoramic and TMJ modes, with all interlock enabled, it is
possible to activate the TEST push button (31) (see Figure 7-7 at the end
of the manual).
The TEST functioning mode allows the operator to check the
functionality of the selected examination cycle or to show to the patient
the examination he will undergo (including all movements of the
machine) without emitting X-rays.
The TEST push button as X-RAY button is a "dead man" button, which
means thus if it is released during the examination cycle, the latter is
interrupted stopping the movements in progress. To re-start the cycle
first reset the unit by means of the key "32" (Figure 7-7), than start again
the function which was interrupted.
