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 V/m.
Recommended separation distances between portable and mobile RF communication
equipment and the Aria 2 Wireless Smart Scale
The Aria 2 Wireless Smart Scale is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Aria 2
Wireless Smart Scale can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the Aria 2 Wireless Smart Scale as recommended below, according to
the maximum output power of the communications equipment.
