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.
ROTOGRAP -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
ROTOGRAP -D and be powered via an independent electric line.
ROTOGRAP -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 and the ear rods.

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 6.6 feet (2 meters) from both the radiation source and
patient.
