1A.9.3 Electromagnetic Compatibility (EMC)
In accordance with the intended use, this X-ray generator complies with the European Council Directive
concerning Medical Devices. The CE marking affixed to this product signifies this. One of the harmonized
standards of this Directive defines the permitted 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 generator. If the other equipment has a comparatively high level of transmission power
and is in close proximity to the generator, these EMC concerns (the risk of interference) may be more
pronounced. It is therefore recommended that the operation of equipment of this type such as mobile
telephones, cordless microphones and other similar mobile radio equipment be restricted from the vicinity
of this X-ray generator.
