WARNING
Read the content of this manual carefully before setting up and adjusting the equipment.
Although this equipment is designed and manufactured in compliance with current safety
standards, any source of X rays always represents a hazard in the hands of an operator
who is not suitably qualified or properly informed. An excessive exposure to X rays can
cause bodily harm.
As a result, all necessary precautions must be taken to avoid unauthorized and unqualified
persons operating this equipment, thus creating a hazard for themselves and others.
Before taking any action, the people qualified and authorized to operate this equipment
must be duly informed on the protective measures specified by the International
Commission on Radiological Protection and on the relevant national norms.
The manufacturer can accept no liability for the effects of any action taken by unauthorized
staff.
The equipment must not be used for any purposes other than those for which it was
intended.
!
The manufacturer declines all responsibility for any failure by authorized technicians to
comply, in the performance of their tasks, with the requirements contained in this manual.
In the event of any anomalies or malfunctions that cannot be overcome by following the
indications given in this manual, the authorized staff must consult the manufacturer of the
equipment to obtain instructions on how to deal with the problem.
This equipment satisfies the requirements of the EEC 89/336 electromagnetic compatibility
directive and subsequent revisions.
To meet said needs, special technical solutions have been adopted, such as the
application of noise filters and the establishing of specific earthing connections. The metal
covers and their closing mechanisms have been manufactured and tested using fixing
devices and special linings made of conducting materials, designed to guarantee both the
equipment's immunity to sources of outside noise and to contain the level of any noise
generated by the equipment's electric circuits.
TECHNICAL AND INSTALLATION MANUAL Pag. II di
27
BT MTEBT03
Technicians performing any maintenance or repairs are consequently strongly
recommended to avoid altering the path of the connections and to scrupulously
reconnect all the earthing connectors relating to the covers, if these are removed
during any maintenance or fault-finding operations, paying the utmost attention to
return the protective covers in the same conditions and with the same fixing
devices as originally installed.
The maximum allowable weight on the patient-positioning table-top is 200 kg.
The manufacturer accepts no liability for the proper operation of the equipment in the
event of its installation or maintenance being handled by unauthorized persons.
The manufacturer reserves the right to make changes to the product described in this
manual at any time, without notice.
Do not stand patients on the table top, or allow them to sit on the end of the table when it
is fully extended.

BT MTEBT03
1.1. GENERAL
The BT is a HORIZONTAL X-RAY TABLE that allows for the four-way movement of the
bucky table, thus facilitating patient positioning for centering them with respect to the X-ray
beam. The surface of the bucky table is perfectly smooth for improved comfort and to
facilitate the transfer of patients on stretchers. The table is floated by means of a foot
pedal which can be placed on the left- or right-hand size, as preferred. The table-top is
fitted with guides on both sides for attaching any accessories. The equipment is fitted with
a longitudinally sliding Potter Bucky (with a mobile grid).
1.2. IMPORTANT ADVICE AND GENERAL NOTES
This manual serves the purpose of providing the manufacturer's staff, or other technicians
authorized by the manufacturer, with instructions for the proper installation and
maintenance of the appliance.

The power and control lines for the X-ray commands are connected to the X-ray generator
by means of the cable prepared during the pre-installation operations. The equipotential
ground node must be connected to the general ground GND node in the X-ray room. The
other electric connections form part of the system wiring, so it is not necessary to provide
further wiring during the installation phase.
The tube stand device STATIX is connected to the BT by connector CN1 on the BTFP02A
board according to the BTFZ10A wiring diagram and using the wires provided.
IMPORTANT!
• The electric system for powering the equipment must be in compliance with the current
regulations applicable to the country where the equipment is installed.
• The manufacturer accepts no liability for any failure to comply with the above
recommendation.

7. MAINTENANCE AND REPAIRS
TECHNICAL AND INSTALLATION MANUAL Pag. 17 di
27
BT MTEBT03
7.1. MAINTENANCE
Before taking any action, it is compulsory for the maintenance technician to stop
the equipment in such conditions that it cannot be started again without his consent
(equipment disabled).
There are cases in which the maintenance technician has to verify the results of certain
operations he has performed or to proceed with a fault-finding session while the equipment
is running. In such cases, specific and indispensable instructions must be given to ensure
that:
• The operator at the controls and the maintenance technician can see each other so that
their communications are easy and unequivocal.
• The operator must act according to the instructions received from the maintenance
technician.
• All maintenance must be done under conditions of adequate lighting.
The maintenance technician must be informed of the exact function of all parts of the
equipment. In the event of any doubts, he must consult the RELEVANT sections of this
manual; he must also pay attention to the signal labels attached to the equipment itself.
Any welding operations on the equipment are likely to cause damage to the
instrumentation and to the electrical and/or electronic devices if these are powered. It is
therefore advisable in this case to disconnect the equipment electrically.
For the first 6 months, and every 12 months thereafter, make the following checks and
adjustments:
⇒ After removing the ABS cover (fig. 8 and fig. 9 par.6.1.1) accurately clean the inside
of the equipment and check that the screws that hold it attached to the floor are tight.
⇒ Check that the moving parts are working properly and lubricate as necessary.
⇒ Check the preservation of the electrical and earthing connections.
⇒ Remove the table-top and accurately clean all the upper parts of the appliance and
lubricate (fig.10 par.6.1.1). Remove any remains of contrast medium from the table
top and Potter cover.
⇒ Potter bucky, clean and lubricate the moving parts (greed support). Remove any
foreign bodies, such as lead numbers and letters.
⇒ Check and, if necessary, adjust the electromagnetic brakes.
⇒ Check the state of wear on the rubber end-of-stroke shock absorbers.
⇒ Check the optical switch brake alignment and function.
⇒ Check and, if necessary, adjust the bearings and their tightness.
Re-install the table-top and any covers that have been removed and check the general
operation of the equipment. Make a mechanical and radiographic test.
