NO TE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NO TE 2 The se guidelines may not apply in all situations. Electromagnetic propagation
is affecte d by absorption and re flection from structures, obje cts and people.
a. Fie ld stre ngths from fixed transmitters, such as base stations for radio
(ce llular/cordless) telephones and land mobile radios, amateur radio, AM and FM
radio broadcast and TV broadcast cannot be predicted theore tically with accuracy.
To assess the e lectromagnetic e nvironment due to fixed RF transmitters, an
e le ctromagnetic site survey should be considered. If the measured field strength in
the location in which the Sm oke Check is used e xceeds the applicable R F compliance
le ve l above, the Smoke C heck should be observe d to ve rify normal operation.
If abnormal performance is observed, additional measure s may be necessary,
such as re -orientating or re locating the Smoke C heck.
O ve r the fre quency range 150 kHz to 80 MHz, field strengths should be less than

Fie lds stre ngths from fixed RF
transmitters, as determined by
an e le ctromagnetic site survey,
should be less than the compliance
