Guidance and manufacturer's declaration - electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below. The
customer or the user of the device should assure that it is used in such an 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
Compliance Electromagnetic environment - guidance
level
Portable and mobile RF communications
equipment should be used no closer to any
part of the device, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
3 Vrms d = 1,2
3 V/m d = 1,2
d = 2,3
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 metres (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:
22
80 MHz to 800 MHz
800 MHz to 2,5 GHz
