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.
Avoiding Electromagnetic Interference (Resp and BIS)
The respiration (Resp) and BIS measurements are very sensitive measurements that measure very small
signals. 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 these measurements.
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.
Emissions test Compliance Avoiding Electromagnetic Interference
Radiofrequency (RF) emissions Group 1 The monitor uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment
RF emissions CISPR 11 Class A The monitor is suitable for use in all establishments other than
domestic and those directly connected to the public low-voltage
power supply network that supplies buildings used for domestic
purposes

environment. If the user of the monitor
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.
