Table 4*
Guidance and manufacturers declaration—electromagnetic immunity
The Liberator is intended for use in the electromagnetic environment specified below. The customer or
the user of the Liberator should assure that it is used in such an environment.
Immunity test IEC 60601 test level Compliance level
Conducted RF
IEC 61000-4-6 150kHz to 80 MHz
Radiated RF
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
a
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be pre-
dicted theoretically with accuracy. To asses the electromagnetic environment due to fixed RF transmit-
ters, an electromagnetic site survey should be considered. If the measured field strength in the location
in which the Liberator is used exceeds the applicable RF compliance level above, the Liberator should
be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the Liberator.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment—guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the Liberator, 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 80 MHz to 800 MHz
d = 2.3 √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
meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site
survery , should be less than the compliance
a
level in each frequency range
