to 80 MHz
3 V Portable and mobile RF communications
equipment should be used no closer to any part of
the AIRO devices including cables, than the
recommended separation distance calculated
from the equation appropriate to the frequency of
the transmitter.
Recommend 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 fixed RF transmitters as
determined by an electromagnetic site survey

,
should be less than the compliance level in each
frequency range.

Interference may occur in the vicinity of
equipment marked with the following symbol:
1. Field strengths from fixed transmitters, such as base stations for radio (cellular/ cordless) telephones and
land mobile radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with accu-
racy. 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 AIRO devices are used ex-
ceeds the applicable RF compliance level above, the AIRO device should be observed to verify normal oper-
ation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the AIRO device.
2. Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.

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.
