Guidance and manufacturer's declaration – electromagnetic immunity
The FT 90/1 is intended for use in the electromagnetic environment specified below.
The customer or the user of the FT 90/1 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 transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which the FT 90/1 is used exceeds the appli-
cable RF compliance level above, the FT 90/1 should be observed to verify normal operation. If abnormal perfor-
mance is observed, additional measures may be necessary, such as reorienting or relocating the FT 90/1.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should
be used no closer to any part of the FT 90/1, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance
Not applicable
d = 1.2
d = 1.2
d = 2.3
where P is the maximum output power rating of the transmit-
3 V/m
ter 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 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:
80 MHz to 800 MHz
800 MHz to 2.5 GHz
