aField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
VZW2556 series of X-ray generators is used exceeds the applicable RF compliance level above, the X-ray
generator should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the X-ray generator.

1.1.6 Electromagnetic Compatibility (EMC)
In accordance with the intended use, some models of this series of X-ray generators comply with the
European Council Directive concerning Medical Devices. The CE marking affixed to compliant products
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.

HIGH VOLTAGE HAZARD: Approximately 400 VAC is present on the membrane console
board in the area of T1, C36, and J5. This is a high voltage source for the fluorescent
backlight on the LCD display.
HIGH VOLTAGE HAZARD: AC mains voltage and / or DC bus voltage (approximately 325 to
670 VDC, depending on model) is present on the H.V. auxiliary board whenever the AC mains
is energized. Ensure that the AC mains is switched off and locked out before servicing this
board. See the note below regarding the DC bus voltage.
HIGH VOLTAGE HAZARD: High voltage is present on all components connected to the AC
mains (line fuses, auxiliary transformer, H.V. auxiliary board, main power contactor, etc)
whenever the AC mains is switched on. Additionally, DC bus voltage is present on certain
components (mains rectifier assembly, DC bus capacitors, inverter assembly, HT tank, H.V.
auxiliary board, etc) whenever the generator is switched on, and will remain on for up to 5
minutes after the console is switched off or the AC mains is switched off or disconnected.
HIGH VOLTAGE HAZARD: Approximately 600 VDC is present on the dual speed starter
board whenever the generator is switched on. This voltage is sourced from the DC bus
capacitors in the generator, and therefore the high voltage hazard will remain for up to 5
minutes after the generator has been switched off.
