Guidance and manufacturer's declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environments listed below, and
should only be used in such environments:
IMMUNITY IEC 60601
TEST TEST LE-
VEL
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 ab-
sorption 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 device is used exceeds themapplicable RF compliance level above, the device should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the device.
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 the device, including cables,
than the recommended separation distan-
ce calculated from the equation applica-
ble to the frequency of the transmitter.

Where P is the maximum output power ra-

ding 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 com-
a
pliance level in each frequency range.
