Electromagnetic Immunity
Basic 30 is intended for use in the electromagnetic environment specified below. The
customer or the user of Basic 30 should assure that Basic 30 is used in such environment.
Immunity
Tests
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4
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 RF 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 pre-
dicted theoretically with accuracy. To assess 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 Basic 30 are used exceeds the applicable RF compliance level above, Basic 30 should be
observed to verify normal operation. If abnormal operation is observed, additional measures may be
necessary, such as reorienting or relocating Basic 30.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of Basic 30, including cables, than the
recommended separation distance calcu-
lated 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 rat-
ing 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
surveya, should be less than the compli-
ance level in each frequency range.
