Avoiding Electromagnetic Interference (Resp)
The respiration (Resp) measurement is a very sensitive measurement that measures a very small signal.
Technological limitations do not allow higher immunity levels than 1 V/m for radiated RF
electromagnetic fields and 1 Vrms for conducted disturbances induced by RF fields. Electromagnetic
fields with field strengths above 1 V/m and conducted disturbances above 1 Vrms may cause
erroneous measurements. Therefore Philips recommends that you avoid using electrically radiating
equipment in the close proximity of this measurement.
WARNING
The monitor should not be used next to or stacked with other equipment. If you must stack the
monitor, you must check that normal operation is possible in the necessary configuration before you
start monitoring patients.
Electromagnetic Immunity
The monitor is suitable for use in the specified electromagnetic environment. The user must ensure
that it is used in the appropriate environment as described below.

requires continued operation during power
mains interruptions, it is recommended
that the monitor is equipped with an
internal battery or is powered from an
uninterruptible power supply.
