Table 3: Electromagnetic immunity 2
Guidance and manufacture’s declaration-electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below. The customer or the user should
assure that it is used in such an environment

Portable and mobile RF communications equipment
should be used no closer to any part of the Patient
Monitor, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
80MHz to 800MHz
800MHz to 2.5GHz
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,
a
should
be less than the compliance level in each frequency
range.
b
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1 At 80MHz 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.
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 the
Patient Monitor is
used exceeds the applicable RF compliance level above, the Patient Monitor should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the
Patient Monitor .
b Over the frequency range 150 KHz to 80 MHz, field strengths should be less than
1V/m(80-800MHz)&3V/m(800-2500MHz).
