Portable and mobile RF communications
equipment should be used no closer to
any part of this product, including cables,
than the recommended separation
distance calculated from the equa-
tion applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1.2 √P 150 kHz to 80 MHz,
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufactur-
er and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmit-
ters, as determined by an electromag-
netic site survey
a
, should be less than
the compliance level in each frequency
range

.
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 con-
sidered. If the measured field strength in the location in which this product is used exceeds
the applicable RF compliance level above, this product should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating this product.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
