the following symbol:
Note
At 80 MHz and 800 MHz, the higher frequency range
applies.
Note
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 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, such as re-orienting
or relocating the Product.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
