environment ‒ guidance
Portable and mobile RF commu-
nications equipment should be
used no closer to any part of the
SD 270 Audiometer, including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
Recommended separation di-
stance
Conducted RF
IEC 61000-4-6
3 Vrms
150kHz to
80MHz
3 Vrms d = 1.2√P
Radiated RF
IEC 61000-4-3
3 V/m
80MHz to
2.5GHz
3 V/m d = 1.2√P 80MHz to 800MHz
d = 2.3√P 800MHz to 2.5GHz
Where P is the maximum out-
put power rating of the trans-
mitter in Watts (W) according
to the transmitter manufac-
turer and d is the recommen-
ded separation distance in
metres (m).
