Radiated RF
IEC 61000-4-3
3 V/m
150 kHz to 80 MHz
3 V/m
80 MHz to 2.5 GHz
3 V/m
Portable and mobile RF communications equip-
ment should be used no closer to any part of
AURICAL Aud, including cables, than the recom-
mended separation distance calculated from the
equation applicable to the frequency of the trans-
mitter.
Recommended separation distance:
d = 1.2
d = 1.2
for 80 MHz to 800 MHz
d = 2.3
for 80 MHz to 2.5 GHz,
where
P
is the maximum output power rating of
the transmitter in watts (W) according to the trans-
mitter manufacturer and d is the recommended
separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of equip-
ment marked with this symbol:
Note 1
: At 80 MHz and 800 MHz the separation distance for 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 AURICAL Aud is used exceeds the applicable RF
compliance level above, the AURICAL Aud should be observed to verify normal operation. If abnormal performance is observed, additional measures might
be necessary, such as reorienting or relocating AURICAL Aud.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
