Guidance and manufacturer's declaration – electromagnetic immunity
The „SAD light" is intended for use in the electromagnetic environment specified below. The customer or the user
of the „SAD light" should ensure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2,5 GHz
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
a site survey should be considered. If the measured field strength in the location in which the appliance is used
exceeds the applicable RF compliance level above, the Medical „SAD light" should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the appliance.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.

environment guidance
Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the „SAD light", in-
cluding cables, than the recommended
separation distance calculated from
the equation applicable to the fre-
quency of the transmitter.
Recommended separation distance
d=1.2√P
d=1.2√P 80 MHz to 800 MHz
d=2.3 √P 800 MHz to 2.5 GHz

where P is the maximum output power
3 V/m rating of the transmitter in watts (W)
according to the transmitter manu-
facturer and d is the recommended
separation distance in metres (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:
