GUIDANCE AND MANUFACTURER'S DECLARATION - ELECTROMAGNETIC IMMUNITY
This X-ray System is intended for use in the electromagnetic environment specified below.
The customer or user of this X-ray System should assure that it is used in such an environment.
Immunity Test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
NOTE 1 - - At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 - - These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a)
Field 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 this Mobile Unit is used exceeds the applicable RF compliance level above, this Mobile Unit should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating this
Mobile Unit.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Level
Portable and mobile RF communications
equipment should be used no closer to any
part of this Mobile Unit, including cables, than
the
recommended
calculated from the equation applicable to the
frequency of the transmitter.

d = 2.3 P

where 'P' is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and 'd' is the
recommended separation distance in meters
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site

), should be less than the compliance
level in each frequency range
