P
is the maximum
output power rating of the
transmitter in watts (W)
according to the
transmitter manufacturer

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 Aria 2 Wireless Smart Scale is used exceeds the applicable
RF compliance level above, the Aria 2 Wireless Smart Scale should be observed to
verify normal operation. If abnormal performance is observed, additional measures
maybe necessary, such as re-orienting or relocating the Aria 2 Wireless Smart Scale.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
