Guidance and manufacturer’s declaration - electromagnetic immunity
The FC1400 system is intended for use in the electromagnetic environment specified below.
The customer or the user of the FC1400 system should assure that it is used in such an environment
Electromagnetic environment -guidance

Field strengths outside the shielded location from fi
xed RF transmitters, as determined by an electrom
agnetic site survey, should be less than 3V/m.a
Interference may occur in the vicinity of equipment
marked with the following symbol:
Note 1) These guidelines may not apply in all situations. Electromagnetic propagation is affected by a
bsorption and reflection from structures, objects and people.
Note 2) It is essential that the actual shielding effectiveness and filter attenuation of the shielded locat
ion be verified to assure that they meet the minimum specification.
a- Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephone
s and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be pr
edicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF trans
mitters, an electromagnetic site survey should be considered. If the measured field strength outside t
he shielded location in which the EUT is used exceeds 3V/m, the EUT should be observed to verify n
ormal operation.
If abnormal performance is observed, additional measures may be necessary, such as relocating the
EUT or using a shielded location with a higher RF shielding effectiveness and filter attenuation.
