Electromagnetic environment –
guidance
Floors should be wood, concrete
±6 kV contact
or ceramic tile. If floors are
±8 kV air
covered with synthetic material,
the relative humidity should be at
least 30 %.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be

Mains power quality should be
that of a typical commercial
or hospital environment. If the
user of the "Daylight" requires
continued operation during
power mains interruptions,
it is recommended that the
"Daylight" be powered from an
uninterruptible power supply or a
battery.
Power frequency magnetic fields

Guidance and manufacturer's declaration – electromagnetic immunity
The "Daylight" is intended for use in the electromagnetic environment specified below. The
customer or the user of the "Daylight" should ensure that it is used in such an environment.
Compliance level
Immunity test IEC 60601 test level
Conducted RF 3 Vrms 3 V
IEC 61000-4-6 150 kHz to 80 MHz 3 V/m
3 V/m
Radiated RF 80 MHz to 2,5 GHz
IEC 61000-4-3
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 "Daylight" is used exceeds the applicable RF compliance level above, the Medical Daylight should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the "Daylight".
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
Electromagnetic environment –
guidance
Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the "Daylight",
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance
d=1.2√P
d=1.2√P 80MHz to 800MHz
d=2.3 √P 800MHz to 2.5 GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufactur-
er and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmit-
ters, as determined by an electromag-
netic site survey,a should be less than
the compliance level in each frequency
range.b Interference may occur in the
vicinity of equipment
