Portable and mobile RF
communications equipment should be
used no closer to any part of the
Product, including cables, than the
recomm
ended separation distance

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. Electromagnet
ic propagation is affected by
absorption and reflection from structures, objects and people.
a) Fixed strength 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 access the electromagnetic environment due to fixed RF
transmitters, and 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 reorienting or relocating the Product.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
