Guidance and manufacturer's declaration-electromagnetic immunity
The AC-80MD is intended for use in the electromagnetic environment specified below. The
customer or the user of the AC-80MD should assure that it is used in such as environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz

environment-guidance
Portable and mobile RF
communications
equipment should be
used no closer to any part
of the AC-80MD,
including cables, than the
recommended separation
distance calculated from
the equation appliance 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
fixed RF transmitters, as
determined by an
electromagnetic site
a
survey, should be less
than the compliance level
in each frequency range.
