Guidance and manufacturer's declaration – electromagnetic immunity
The model BASE800 is intended for use in the electromagnetic environment specified below.
The customer or the user of the model BASE800 should assure that it is used in such an environment.
Immunity test IEC 60601test
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
80 MHz to 2,5 GHz
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.

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
model BASE800 is used exceeds the applicable RF compliance level above, the model BASE800 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the model BASE800.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than V/m.

guidance
Portable and mobile RF
communications equipment should be
used no closer to any part of the model
BASE800, 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 0 MHZ to 800 MHZ 8
d = 2,3 P 00 MHZ to 2,5 GHZ 8
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,
less than the compliance level in each
