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 product is used exceeds
the applicable RF compliance level above, the product should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m.
Caution:
Operating the product near a strong electro-magnetic field may affect the displayed weight
measurement.
These changes does not affect user safety.
