Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The EPS 45-80 High-Voltage X-ray generator is intended for use in the electromagnetic environment specified below.
The customer or the user of the EPS 45-80 High-Voltage X-ray generator should assure that it is used in such an
environment.

transmitter.

Field strengths fixed RD transmitter, as determined
by an electromagnetic site survey, a should be less
than the compliance level in each frequency range.b
Interference may occur in the vicinity of equipment
marked with the following symbol:
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 the EPS 45-80 High-Voltage X-ray generator is used
exceeds the applicable RF compliance level above, the EPS 45-80 High-Voltage X-ray generator should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the EPS 45-80 High-Voltage X-ray generator.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
