Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
ARTROMOT®-S3 is intended for use in the electromagnetic environment specified below. It
is the responsibility of the customer or user to ensure that the ARTROMOT®-S3 unit is used
in such an environment.
Immunity test IEC 60601

environment - guidance
Portable and mobile RF commu-
nications equipment should be
used no closer to any part of the
ARTROMOT®-S3 unit, including
cables, than the recommended sepa-
ration distance calculated from the
equation applicable to the frequency
of the transmitter.
Recommended separation distance:
Conducted RF to
IEC 61000-4-6
3 Vrms
150 kHz to
80 MHz
3 Vrms d = 1,2 √P
d = 1,2 √P at 80 MHz to 800 MHz
d = 2,3 √P at 800 MHz to 2,5 GHz
where P is the maximum output
power rating of the transmitter in
watts (W) according to the trans-
mitter manufacturer and d is the
recommended separation distance in
meters (m).
Radiated RF to
IEC 61000-4-3
3 V/m
80 MHz to
2.5 GHz
3 V/m Field strengths from fixed RF trans-
mitters, as determined by an elec-
tromagnetic 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 fol-
lowing 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.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cord-
less) telephones and land mobile radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic envi-
ronment due to fixed RF transmitters, an electromagnetic site survey should be con-
sidered. If the measured field strength in the location in which the ARTROMOT®-S3
exceeds the applicable ARTROMOT®-S3 unit should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be neces-
sary, such as reorienting or relocating the ARTROMOT®-S3 unit.
b) Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
