Portable and mobile RF communications equip-
ment should be used no closer to any part of the
Device ,including cables, than the recommended
separation distance calculated from the equation
appropriate for the frequency of the transmitter.
Recommended separation
distances:

d=2√P

by an electromagnetic site

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 [XXXXX] is used exceeds the
applicable RF compliance level above, the [XXXXX] should be observed to verify normal operation. If abnormal per-
formance is observed, additional measures may be necessary, such as re-orienting or relocating the [XXXXX].
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
