Portable and mobile RF communications
equipment should be used no closer to
any part of the model IRT101B/IRT101,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.
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:
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 model IRT101B/IRT101
is used exceeds the applicable RF compliance level above, the model IRT101B/ IRT101
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the model
IRT101B/IRT101.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
