Guidance and Manufacturer’s Declaration of Electromagnetic Immunity
The X-ray detector is intended for use in the electromagnetic environment specified below. The installer,
X-ray system manufacturer, or user of the X-ray detector should assure that it is used in such an
environment.

in watt (W) according to the transmitter
manufacturer and
d is the recommended
separation distance in meter (m).

fixed RF transmitters, as determined by an

, should be less than
3 V/m.
Interference may occur in the vicinity of equipment
marked with the following symbol.
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 mea-
sured field strength in the location in which the X-ray detector is used exceeds the applicable RF compliance level above, the
X-ray detector 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 detector.
Note 1: These guidelines may not apply to all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
Note 2: It is essential that the actual shielding effectiveness and filter attenuation of the shielded location
be verified to assure that they meet the minimum specification.
