where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer
and d is the recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site surveya, should be less than the
compliance level in each frequency rangeb.
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 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
measure field strength in the location in which the FL1401 is used exceeds the applicable RF compliance level above, the
FL1401 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the FL1401.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3.0 V/m.
NOTE 3: U

Electromagnetic environment – guidance
Floors should be wood, concrete or ceramic tile. If floors are covered with synthetic material, the relative humidity
should be at least 30%.
Mains power quality should be that of a typical commercial or hospital environment.
Mains power quality should be that of a typical commercial or hospital environment.
Mains power quality should be that of a typical commercial or hospital environment. If the user of the FL1401
requires continued operation during power mains interruptions, it is recommended that the FL1401 be powered
from an uninterruptible power supply or a battery.
Power frequency magnetic fields should be at levels characteristic of a typical location in a typical
commercial or hospital environment.
Portable and mobile RF communications equipment should be used no closer to any part of the FL1401, including
cables, than the recommended separation distance calculated from the equation applicable to the frequency of the
transmitter.
