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 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:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorp-
tion and reflection from structures, objects and people.
a Field strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radios 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
Domotherm

is used exceeds the applicable RF compliance level above,
Domotherm

should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating
Domotherm

b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
