Safety Information Application The MOBILETTs are mobile radiographic systems designed for use in wards, intensive care and premature-birth wards, emergency departments, operating theatres as well as the central X-ray department.

Special Features • Combined battery/mains power operation, MOBILETT Plus HP only • High output enables short exposure times down to 1 ms • Integrated turn plate to facilitate positioning at the patients bed, MOBILETT Plus/ Plus HP only • Double articulated arm system for extended reach • Small and compact for quick and easy handling.

Maintenance To ensure the safety of the patients, the operators, and third parties, the equipment must be checked every 12 months to maintain its reliability and serviceability according to the maintenance checklist. All parts of the MOBILETTs which, if worn, may create a safety hazard, must be checked by skilled personnel at regular intervals of 12 months, and replaced, if required. This should be done by the Siemens customer service department within the framework of maintenance. If national rules or regulations specify more frequent checking and/or maintenance, this must be observed.

Checks, Test Before using the equipment for examination, the user must ascertain that all safetyrelevant devices function properly and that the MOBILETT is ready for operation. Special attention must be given to checking the displays and pilot lights for proper operation (visual check). Perform the checks and tests according to the daily check list. The radiation indicator may light during operation only while the radiography switch is operated. In the event that this lamp lights while this switch is not operated, the MOBILETT must be shut down at once and customer service must be notified.

Safety Information Installation, Repair Modifications of, or additions to the MOBILETT must be made in accordance with the legal regulations and generally accepted engineering standards. As manufacturers, assemblers, installers or importers Siemens cannot assume responsibility for the safety features and for reliability and performance of the equipment, specially if: • installation, equipment expansions, readjustments, modifications or repairs are not carried out by persons authorized by us. • components affecting safe operation of the MOBILETT are not replaced by original spare parts in case of malfunction. • electrical installation of the room concerned does not meet the requirements of the VDE 0107 regulation, or the corresponding national regulations, or • the MOBILETT is not used in accordance with the instructions for use. On request, we will make technical documents for the product available to you at a charge which will be invoiced. This does not imply an authorization to undertake repairs. We accept no responsibility for repairs performed without our expressed written approval. We suggest that you obtain a report indicating the nature and extent of the work performed, from the persons carrying out such work, and specify that the report show any changes in rated parameters or operating ranges, as well as the date, the name of the firm, and a signature.

Safety Information Emergency shutdown The mains connector must be easily accessible so that the unit can be quickly disconnected from the mains if there is a safety hazard.

Fire Protection In case of fire, switch off the MOBILETT immediately (for MOBILETT Plus HP turn the main switch to C) and pull the power cable out of the wall outlet.

WARNING! A fire or smouldering fire can produce toxic gases or vapours. We strongly recommend that all personnel is informed of correct procedures in case of fire as part of occupational safety training. When clean-up and restoration work is completed, contact Siemens customer service prior to restarting the MOBILETT.

Explosion Protection The MOBILETT is not designed for operation in areas where there is an explosion hazard.

Radiation Protection For the Patient • Keep the radiation field as small as possible. • Provide the best possible protection for reproductive organs (gonad protective caps or lead-rubber covers) during exposure in the vicinity of these organs.

For the Operating Personnel • When releasing the exposure, there must always be sufficient protective distance between the operator and the X-ray tube assembly. • Wear protective clothing (lead-rubber apron), if you must be in close vicinity to the patient during an exposure! • Wear a radiation monitoring badge or a pen dosimeter if necessary.

Both for the Patient and the Operating Personnel • When operating the remote control make sure that there are no other infrared remote controlled systems in line-of-sight. This includes systems behind a window or lead glass. Other infrared remote controlled systems in line-ofsight should be powered down when operating the MOBILETT with the remote control, to avoid possible interference.

Functional Description Tilting the MOBILETT

MOB00282

The unit has two support wheels to facilitate the movement over thresholds and similar obstacles. When passing a threshold or similar obstacle the front wheels can be lifted by pressing down by hand the transport handle.

16

Functional Description Arm System The MOBILETT is provided with a counterbalanced, double articulated arm system. The X-ray tube assembly and the arm system remain in position without any additional locks.

Hand/Parking Brake When transporting the MOBILETT on inclined planes (>2°) always be prepared to use the hand brake in case of an emergency. The hand brake also serves as a parking brake. Pull the handle upwards and to the left into park position. To release the parking brake, pull the handle upwards and then push to the right.

CAUTION! There is a risk that the MOBILETT may tilt over, if the inclination exceeds 10°. The parking brake ensures braking at an inclination of up to 10° only.

MOB00284

Hand/Parking brake

Potential equalizer The MOBILETT can be connected to a Protective Earth Terminal with the potential equalizer connector found next to the transport safeguard (see Parts and Controls (page 9). This will ensure that the MOBILETT has the same electrical potential as other units connected to the same Protective Earth Terminal.
