Although this equipment was designed and manufactured according to the most up-to-date safety standards,
the source of X-rays is always dangerous when the operator is not properly qualified or trained. Excessive
exposure to X-rays damages the human body.
Therefore, all the necessary precautions must be taken to prevent unauthorized or unskilled personnel from
operating this equipment, thus jeopardizing themselves and other people. Do not use the equipment if you
have not received appropriate training in the correct and safe use of the equipment itself by the manufacturer
or any of his appointed instructor. Before executing any operation, the persons qualified and authorized to
operate this equipment must be informed about the protection and safety measures established by the
International Committee for Radiological Protection, as well as any other relevant national Standards.
For proper use of this equipment, it is necessary that the operator refer preventively and carefully to this
User’s manual. Special attention should be paid to the sections concerning User Interface, Command
Functions, Application Examples, Safety Recommendations and Protection Measures. Incorrect and
inappropriate use of the machine by poorly qualified personnel who are unsuitable and insufficiently
trained can cause fatal accidents.
N.B.
This device is in compliance with the requirements established by the European Directive 2007/47/EC which
amends the Directive 93/42/EEC regarding medical devices, thus it bears the EC mark stating the code number
identifying the notified body responsible for carrying out the procedures foreseen for the compliance
certification.
This is a Class IIb device according to Rule 10 of Annex IX to Directive 93/42/EEC and following amendments
and additions.
The manufacturer declines all responsibility with regard to the proper functioning of the equipment, should
the installation or the maintenance of it be executed by unauthorized personnel.

GENERAL MEDICAL MERATE S.P.A. CODE 62235 - REVISION 13
1.6. Electromagnetic compatibility (EMC)
In accordance with the intended use, this remote controlled Table complies with the European Directives
concerning Medical Devices. The CE marking affixed to this product signifies this. One of the standards of this
directive defines the allowed levels of electromagnetic emission from this equipment and its required
immunity from the electromagnetic emissions of other devices.
It is not possible, however, to exclude with absolute certainty the possibility that other high frequency
electronic equipment, which is fully compliant to the EMC regulations, will not adversely affect the operation
of this system. If the other equipment has a comparatively high level of transmission power and is in close
proximity to the system, these EMC concerns (the risk of interference) may be more pronounced. It is
therefore recommended that operations with mobile or cordless telephones, microphones and other similar
equipment, such as mobile radio systems, are strictly executed away from the R&F device.

2.3.1.3. DR flat panel detector
Instead of the normal film/CR cassette a DR flat panel detector can be used which is available in two versions:
- 35x43 cm useful area ‐ wireless mobile
- 43x43 cm useful area - tethered fixed (with I.I. up to 12”)
The 35x43 cm wireless is a “cassette like” DR flat panel, thus it can be inserted in the SFD like any normal
film/CR cassette.
With a special version of OPERA DFR digital system it is possible to acquire both RF camera images and DR
panel images using one console only.
2.3.1.4. R&F flat panel detector
A full digital solution can be chosen for both fluoroscopic and radiographic imaging. This solution is based on
OPERA D4000RF digital system and PIXIUM RF4343 flat panel detector designed to replace conventional R&F
radio‐diagnostic systems based on conventional film/CR cassette with SFD and fluoroscopy systems with
image intensifier.
2.3.2. Collimator
For further information, see chapter 11.
2.3.3. Compressor
The remote controlled compressor allows an effective though not traumatic palpation; the compression force
can be adjusted up to 200 N.
A special consideration has been devoted to mechanical and electrical safety, as well as safety against wrong
manoeuvres. The compressor has a parking position from which it automatically moves in and out.
An alternative compression system with three interchangeable cones without automatic parking feature is
available, as optional accessory. For further information, see chapter 12.
2.3.4. Grid
Tables with focal distance (SID) up to 150 cm are equipped with a single grid system.
Tables with focal distance (SID) up to 180 cm can be equipped with a dual grid system to ensure optimal
radiological conditions during any exposure. The system will automatically set the proper grid focalization
based on the selected SID. The grid can be automatically parked to ensure low dose in pediatrics applications
and for extremities examinations.
To use the single grid device is however possible on tables with SID up to 180 cm.
In addition, a high focalization grid is also available.
N.B. The dual grid system is not available for SFD version with crossed subdivisions

GENERAL MEDICAL MERATE S.P.A. CODE 62235 - REVISION 13
2.3.5. Control console
The control console represents the main contact point between the operator and system.
Considerable care was therefore dedicated to this important element especially concentrating on integration
of the various components commands: remote controlled table, generator and digital system (if present).
Various console configurations are available:
- Single table console
- Table and generator integrated console with push button
- Table and generator integrated console with touch screen
The control console can be supported by a floor stand or placed on desk.
The main control console layout depends on the equipment configuration (see chapter 5).
A secondary, on-trolley console with joystick is available, as an option, for the examination room (see chapter
6). This console allows the operator to control all the table movements, while remaining next to the patient.
This manual contains all the information on operating the examination table and the user interface. For
specific information regarding the single components such as the digital system, the generator and the
collimator, please refer to the respective operator’s manual.

2.4. Performance
2.4.1. Tilting
Tables can be chosen either with 90°/30° tilting system that considerably reduces the overall dimensions of
the equipment or with 90°/90° tilting to make the equipment completely symmetric. Thanks to this
characteristic the footrest can be positioned at either one table extremity or at the other, according to the
user's choice so that the most suitable condition can be defined with respect to the room entrances and the
position of the anti-X-ray booth.
Tabletop‐to‐floor distance is 86 cm both with 90°/30° and 90°/90° tilting.
The elevating 90°/90° tilting allows for setting tabletop‐to‐floor distance from 76 to 100 cm.
2.4.2. Tabletop
Tabletop can be chosen with 210 cm or 240 cm length.
The 210 cm length realizes an extremely compact table without any limitation.
The 240 cm length allows great patient explorations without repositioning.
The tabletop movements are extremely ample:
35 cm in the transversal direction
in longitudinal direction (optional):
- 160 cm (±80 cm ) with 210 cm tabletop length,
- 160 cm (±80 cm ) or 120 cm (+100/‐20 cm) with 240 cm tabletop length.
The table structure allows the operators to move easily towards the patient from any side. The patient gets
on/off easily from the table both in horizontal and in vertical.
When the table is in vertical position, if the tabletop longitudinal movement is available, it is possible to lower
the tabletop in order to ease getting on the footboard for patients with motion difficulties. For safety reasons
this operation can be commanded only from the on‐board console.
Particularly high is the patient's maximum admitted weight: 230kg without any limitations of use, up to 260kg
with limitation of use (static exams).
2.4.3. X-ray tube stand
The extended displacements of the stand make the OPERA T tables very supple.
Longitudinal displacement with image system ‐ 210 cm tabletop length:
- 124 cm, without longitudinal tabletop movement
- 108 cm with longitudinal tabletop movement.
Longitudinal displacement with image system ‐ 240 cm tabletop length:
- 154 cm, without longitudinal tabletop movement
- 138 cm with longitudinal tabletop movement.
Focus‐film distance:
- continuously variable focus‐film distance with preset positions at 115, 135, 150 and optionally 180.
High quality imaging for cardiac and chest examinations is therefore assured.
Oblique incidences:
- 40° ensure the execution of complete examinations of the spine with different incidences
in addition, the capability of layer height selection allows the operator to maintain the object to be
examined always centred on the image.
X‐ray tube assembly rotation:
- 270° with mechanical detents placed at 0°, ±18°, ±36°, ±54° ±72°, ±90° and ‐180° to allow easy execution of
examinations with cassette outside SFD, on wall bucky stand and on stretcher.
Minimum distance between X‐ray beam and table edge:
- 43 cm, makes it easy to execute effective uro‐gynaecological examinations
Page 26
OPERATOR'S MANUAL OPERA T
August 2020
Page 22/135
GENERAL MEDICAL MERATE S.P.A. CODE 62235 - REVISION 13
Due to its special structure, the table placed in vertical position ensures a great diagnostic efficiency:
- extended and easy execution of examinations on charged legs, thanks to the reduced focus‐floor distance
- examinations on stretched patients proves to be very easy since the operator can count on a large focusfloor distance and wider space for patient positioning, thanks to the ample longitudinal displacement and
long focal distance.
2.4.4. Linear tomography
OPERA T performs high level linear tomography acquisitions; digital control ensures high accuracy and
precision.
Main performances:
- possibility of execution from ‐90°(‐30°) up to 90°, with scan in both directions
- angles: 5°, 8°, 20°, 30°, 40°; (the angles 5°, 30° are not available in case of configuration with DR digital
detector)
- two speeds for each angle
- possibility to change from linear tomography to radiography on the same cassette
- selection of the layer height from 0 to 330 mm
- automatic increase of the layer height between 1 and 10 mm pre‐arranged during installation.

2.7. Diagnostic room: typical layout
The manufacturer proposes the layout of a typical diagnostic room, similar to the one seen in the above
picture, which gives the operator complete visual contact with moving tabletop and monitor the patient even
from the remote control station. If it is not possible to use this layout, the manufacturer and clinic engineer
will assess all possible solutions to guarantee a safe working environment, eliminating all possible risks.
If the control console (1) is installed in other positions, (for instance laterally with respect to the tabletop), the
operator and patient are both exposed to risks caused by lack of visibility when the machine is moving.
The next section provides some advice on how to guarantee the operator complete control of all movement
activities:
1. Remove the patient footrest when working in a horizontal direction with the patient on the tabletop.
2. If necessary, arrange some mirrors which ensure the patient can be monitored even in positions where
the tabletop hides the patient from view.
3. ALWAYS watch the machine and the patient when performing all movements.
The same assessments must be made for small diagnostic rooms as the settings of the dedicated software
controlling certain movements of the machine can be adjusted to suit such areas during the installation
phase.

GENERAL MEDICAL MERATE S.P.A. CODE 62235 - REVISION 13
4. EQUIPMENT STARTUP PROCEDURE AND “MOVEMENT ENABLE” CONTROL
4.1. Equipment startup procedure
Upon switching on or resetting the safety/emergency status in the room or on the equipment, the following
examination table initialisation procedure is performed. During this procedure, the transmissions of the spot
film device, the I.I. and the focal distance (if installed) perform a series of automatic movements before
allowing the equipment to be used.
In systems with a 16" (40cm) adjustable table and I.I., if the table is at an elevation height of less than 60 mm,
the initialisation procedure is interrupted to prevent the I.I. from hitting the floor.
The Adjustable tabletop height – Tilting angle display (5,6,7) will start flashing on the main control console
indicating reduced functionality of the system (it is not possible to perform spot film device examinations).
To obtain full functionality of the equipment in this condition, the operator must raise the examination table
to a height of over 60 mm to permit completion of the initialisation procedure.
It is recommended to leave the equipment in position (elevation above 60 mm) before switching it off; this
will generate complete initialization of the tabletop without interruptions.
4.2. “Movement enable” control
If error code 97 is indicated on the (2,3,4) display when the equipment is switched on, one or more push
buttons, or tabletop displacement joystick on the console or remote control keyboard have malfunctioned or
have been pressed by mistake during startup.
On detecting the cause of the error, proceed as follows:
If the push-button/joystick has been pressed by mistake during startup:
Release the push-button or joystick
Turn the equipment off and then on again
If the push-button /joystick has not been pressed (malfunction), it is possible to use the equipment in
reduced operating mode, following the procedure below:
Press the (55) push-button to reset error code 97
Check all the table movements to detect which movement is inhibited; in emergency
situations use the equipment avoiding this specific movement.
Contact Technical Assistance to repair the malfunction.

The spot film device with 2,3,4 bands or stripes allow the division of any size in the transversal direction;
The division in 5, 6 bands or stripes is only possible for sizes over 24cm or 10 inches.
The crossed spot film device in addition to the division of any size in a transversal direction, also allows
the crossed subdivision in 4 and 6 for the 18x24, 24x24, 24x30 sizes.
The LED placed on each push-button indicates the division currently selected.
The number of available exposures is always displayed according to the selected program. In addition, when
the cassette holder is in the parked position in the spot film device, it is possible to read the dimension of the
cassette inserted in the spot film device by pressing the selected cassette division button.
The selected film size division automatically determines the automatic collimation of the X-ray beam, with the
command: "Radiography preparation".
At each "Radiography" command, the division program advances one step while the number of available
exposures shown on the display decreases. After exposing the final section of the film, the cassette is
automatically sent to its parking position. The display will indicate that the division program is over (0
radiographs available) and it is not possible to perform any further radiographic exposures.
It is always possible to insert a radioscopy between one radiographic exposure and another by pressing the
radioscopic foot pedal. The following radiographic exposure will be executed by turning back to the point
where the division program was last interrupted.
When the radiographic exposure series is over, you can only perform other exposures after replacing the
radiographic cassette. When you replace the radiographic cassette, the division program last selected will
remain active.

WARNING
Incorrect installation of the on-board console with joystick can cause damage to patients,
operators and equipment.
The optional on-board joystick controls the patient scanning
displacement:
Move the joystick up or down to effect longitudinal
patient scanning through the positioning of the
stand/spot film device.
Move the joystick to the left or right to effect
transversal patient scanning through the positioning of
the tabletop in a transverse position.
The movements were programmed so that a “topographic”
correspondence is obtained compared with the image
showed on the monitor.
In order to use the on-board joystick to control the table displacement, it is necessary to
move the lever and simultaneously press the “enable movements” push-button which is
positioned near the remote keyboard (on-board control panel).
Pushing the joystick to the right will achieve lateral displacement of the tabletop towards the
internal side, corresponding to screen image shifting to the right.
Pushing the joystick to the left will achieve lateral displacement of the tabletop towards the
external side, corresponding to screen image shifting to the left.
Pushing the joystick forwards will achieve the displacement of the I.I.-X-ray tube stand group
towards the left side of the longitudinal axis, corresponding to screen image shifting
upwards.
Pushing the joystick towards the operator (backwards) will achieve the displacement of the
I.I.-X-ray tube stand group towards the right side of the longitudinal axis, corresponding to
screen image shifting downwards.
With table tilting wider than ±85° and X-ray group rotated (not centred on the SFD or
detector), by driving the oblique incidence lower the movement will stop at 140 cm from the
floor. It is necessary to release it and repeat the command to continue the displacement
operations. Displacement will be enabled again at minimum speed.

turn clockwise to open them and counter clockwise to close them.
11.3. DFR technique
This technique is present if the DFR push button (14) (on the main consol panel) has been selected.
It is possible to change the X-ray field within the limits of the I.I. size that was previously selected by means of
the push-buttons (1, 2, 3, 4) (on themain console panel)
11.4. X-ray cassette technique
Below the adjustment knobs (B) there are special graduated scales (C): at each segment it corresponds a
collimator aperture over the cassette or over the image intensifier related to focal distance frontal panel
table (D).
The table on the front panel shows the number to set with the knobs. The number to set is read by crossing
the FFD in use cm or in inch (vertical arrow E ) with the cassette size in cm on inches (horizontal arrow F).
Move the knob index to place it on the scale value corresponding to the requested measure/value.
11.5. X-ray field adjustment for “External Radiographs”
