SAFETY WARNINGS A few safety recommendations are listed below which should be followed when using the “X-Mind DC” radiographic system. PROTECTION AGAINST RADIATION “The general principles regarding safety and protection of workers and people” must always be applied when using the unit: 1. Justification of the practice 2. Protection Optimization (ALARA) 3. Reduction of individual dose limits and risks The X-ray system may only be used by authorized and qualified personnel. All personnel present during the radiological examination must comply with safety measures established with respect to radiation protection. For his or her own safety, the operator must always remain at least 2 meters from the tube head. To protect the patient from unnecessary exposure to radiations, additional anti-radiation protection may be used whenever necessary (i.e. aprons, collars, etc…)
This symbol calls ATTENTION to the danger of X-rays
ELECTRICAL SAFETY The X-ray system contains high voltage. When inspecting internal parts, always turn off the power before handling any electrical part. The unit must be used only in environments which comply with all electric safety standards for medical environments. The unit is NOT equipped with protection against penetration by liquids; it is therefore necessary to ensure that no water or other liquids penetrate the device, in order to avoid short circuits or corrosion. Always disconnect the X-ray system from the power supply before cleaning and disinfecting operations.
MECHANICAL RISK Before removing the tube head from the positioning arm, RELEASE THE SPRING, as the joint might burst open and hit the operator.
PROTECTION AGAINST EXPLOSIONS The X-ray system MUST NOT be used in the presence of disinfectants, flammable or potentially explosive gases or vapors which might catch fire and cause damage. In the event that disinfectants must be used, allow the vapor to disperse completely before turning on the X-ray system.

3. IDENTIFICATION TAGS
The “X-Mind DC” x-ray system (Fig. 1) consists of: c Tubehead
The tubehead is of the “monoblock” type with following characteristics: high frequency generator at “constant potential” double anode voltage 60kVp – 70kVp double anode current 4mA – 8mA The light alloy housing is divided into two compartments. The high voltage transformer, the X-ray tube and the expansion chamber are submerged in highly dielectric insulating oil inside a light alloy container. The second compartment contains the electronic main board and the electronic control board. The X-ray tube is located in the back part of the housing thus allowing a focal spot to skin distance (SSD) which is 50% higher than the traditional structure. d Spacer Cone Made of transparent polycarbonate, it allows for: correct focal spot to skin distance dimension, direction and centering of the X-ray beam use of different x-ray techniques (bisecting and parallel techniques) e Pantograph type arm Thanks to the new shape and new mechanisms of the positioning arm, the height and depth can be adjusted so as to precisely explore any spot in its reach. It is made of light alloy with an “ABS” coating. f Timer The timer is the control panel used to manage the times and to safely use the tubehead. It is “multi-technology” type and it is able to control both AC and DC x-ray systems. The “CONTROL BUTTON” with safety button is used for the exposure. The timer can be connected to n° 2 tubeheads: n° 2 ALTERNATE CURRENT “AC” X-RAY UNITS: “X-Mind AC” or n ° 2 DIRECT CURRENT “DC” X-RAY UNITS: “X-Mind DC” or n ° 1 ALTERNATE CURRENT “AC” + n° 1 DIRECT CURRENT “DC” X-RAY UNITS: “ X-Mind AC ®” + “X-Mind DC” OPTIONAL − short 8” (20 cm) cone – NOT AVAILABLE IN U.K. − long cone 12” (31 cm) with a rectangular section - dimensions: 44x35 mm − second “CONTROL BUTTON” with extension cable − RX signaling lamp for external use: X-Mind LIGHT − remote control button: X-Mind ECB
The identification tags on the tubehead, on the timer and on the cone indicate the model name, the serial number, the manufacturing date and the symbols of the main technical characteristics.

B. The following exposure times have been stored in the “xminddc” x-ray system: 0.020 – 0.025 – 0.032 – 0.040 – 0.050 – 0.063 – 0.080 – 0.100 –0.125 – 0.160 – 0.200 – 0.250 – 0.320 – 0.400 – 0.500 – 0.630 – 0.800 – 1.00 – 1.250 – 1.600 – 2.000 – 2.500 – 3.200 sec PLEASE NOTE These times comply with current CEI EN 60601-2-7 (1999) standards and with the ISO 497 series R’10 recommendations. This programmed exposure times MAY NOT be modified. C. In the “X-Mind DC” x-ray system to further simplify and speed up the operations to select times of exposure, certain exposure times have been predefined which depend on: the x-ray distance: 12” or 8” the x-ray technique: FILM or DIGIT the patient’s body size: ADULT or CHILD the type of intra-oral test: PERIAPICAL, OCCLUSAL, BITE-WING PLEASE NOTE If one so desires, it is possible to change the “PREDEFINED EXPOSURE TIME VALUES” (refer to §9 “PROGRAMMING DEFAULT EXPOSURE VALUES”)
