APPENDIX II
Guidance and manufacturer's declaration – electromagnetic immunity
The patient care monitors are intended for use in the electromagnetic environment specified below. The
customer or the user of the monitor should assure that they are used in such an environment.
Immunity test
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
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.

Appendix II-3
Electromagnetic environment –
level
Portable and mobile RF communications
equipment should be used no closer to any
part of the monitor) including cables, than
the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d = 1.17 P
d = 1.17 P 80 MHz to 800 MHz
d = 2.33 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 survey,
less than the compliance level in each
frequency range.
Interference may occur in the vicinity of
equipment marked with the following
