3.2.4 Guidance and manufacturer’s declaration –
electromagnetic immunity
The Monitor is intended for use in the electromagnetic environment specified below. The
customer or the user of the Monitor should assure that it is used in such an environment.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the 90217/90217A, including patient cables,
than the recommended separation distance
calculated from the equation applicable at the
frequency of the transmitter: Recommended
separation distance
Conducted RF IEC

3 V/m d = 1.2 √ P 80 MHz to 800 MHz = 2.3 √ P 800
MHz to 2.5 GHz
where P is the maximum output power of
the transmitter in watts (W) according to
the transmitter manufacturer and d is the
recommended separation distance. 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 adjacent symbol:
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.
* 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 device is used exceeds the applicable RF compliance
level above, the device should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the device.
** Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
