Immunity test IEC 60601 test
Conducted RF 3 Vrms 150 kHz
IEC 61000-4-6 to 80 Mhz
Radiated RF 3 V/m 80 Mhz
IEC 61000-4-3 to 2.5 Ghz
IMPORTANT: At 80 MHz and 800 MHz, the higher fre-
quency range applies.
IMPORTANT: 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
a
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 electro-
magnetic environment due to fixed RF transmitters,
an electromagnetic site survey should be consid-
ered. If the measured field strength in the location
in which the Zen-O™ is used exceeds the applicable
RF compliance level above, the concentrator should
be observed to verify normal operation. If abnormal
performance is observed, additional measures may
be necessary, such as reorienting or relocating the
concentrator.
Over the frequency range 150 kHz to 80 MHz, field
b
strengths should be less than 3 V/m.

Electromagnetic environment/
guidance
Portable and mobile RF communi-
cations equipment should be used
no closer to any part of the device,
including cables, than the recom-
mended separation distance calcu-
lated from the equation applicable
to the frequency of the transmitter.
Recommended separation
distance:
d = 1.2 √P 150 kHz to 80 MHz
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 transmit-
ter manufacturer and d is the
recommended separation distance
in meters (m).
Field strengths from fixed RF trans-
mitters, as determined by an elec-
tromagnetic site survey
less than the compliance level in
each frequency range
