Guidance and manufacturer's declaration – electromagnetic immunity
The Baha 5 SuperPower is intended for use in the electromagnetic environment specified below. The customer
or the user of the Baha 5 SuperPower should assure 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.
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
Baha 5 SuperPower is used exceeds the applicable RF compliance level above, the Baha 5 SuperPower should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Baha 5 SuperPower.
b: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 6 V/m.
Compliance Electromagnetic environment –
level guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the Baha 5 SuperPower, including cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
6 Vrms d=0.58√P
10 V/m d=0.35√P 80 MHz to 800 MHz
d=0.70√P 800 MHz to 2.5 GHz
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 metres
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in each
frequency range
Interference may occur in the vicinity of
