Guidance and manufacturer's declaration – electromagnetic immunity
The FT 100 is intended for use in the electromagnetic environment specified below.
The customer or the user of the FT 100 should assure that it is used in such an environment.
Immunity test IEC 60601 test
level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
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 transmit-
ters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the FT 100 is used exceeds the applicable
RF compliance level above, the FT 100 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the FT 100.
b
. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.

level
Portable and mobile RF communications equipment should be used no closer to any part of the
FT 100, including cables, than the recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
3 Vrms
d = 1.2
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 MHz to 2.5 GHz
3 V/m where P is the maximum output power rating of the transmitter in watts (W) according to the trans-
mitter manufacturer and d is the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey
should be less than the compliance level in each frequency range
