Portable and mobile RF communications equipment should
be used no closer to any part of this device, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance
d=[1.2] √P
d=[1.2] √P 80 MHz to 800 MHz
d=[2.3] √P 800 MHz to 2.5 GHz
where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer and d is
the recommended separation distance in meters (m).
Field strengths from xed RF transmitters, as determined by
an electromagnetic site survey
a
, should be less than the com-
pliance level in each frequency range
b
.
Interference may occur in the vicinity of equipment marked
with the following symbol:
[NOTE] At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
[NOTE] These guidelines may not apply in all situations. Electromagnetic propagation is a󰀨ected by absorption and reection
from structures, objects and people.
a Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be considered. If the mea-
sured eld strength in the location in which this device is used exceeds the applicable RF compliance level above, this device
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating this device.
b Over the frequency range 150 kHz to 80 MHz, eld strength should be less than [3] V/m.
