Guidance and manufacturer's declaration – electromagnetic immunity
The Curapuls 670 is intended for use in the electromagnetic environment specified below. The customer
or the user of the Curapuls 670 should assure that it is used in such an environment.
Immunity test
Conducted RF
IEC 61000-4-6
Radiated RF
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.
A 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 Curapuls 670 is used exceeds the applicable RF compliance level above, the
Curapuls 670 should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the Curapuls 670.
B Over the frequency range 15 kHz to 8 MHz, field strengths should be less than 3 V / m.

Portable and mobile RF
communications equipment should be
used no closer to any part of the
Curapuls 670, including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
3 V d = [3,5/3]√P
d = [3,5/3]√P
3 V/ m
d = [7/3]√P
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and d is the
recommended separation distance in
meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
less than the compliance level in each
frequency range.
