ELECTROMAGNETIC COMPATIBILITY
Guidance and manufacture's declaration - electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below. The customer or the user of the device
should assure that it is used in such an environment.
Immunity Test
IEC 60601 test level
Conducted RF
150 kHz to 80 MHz:
IEC 61000-4-6
3 Vrms
6Vrms (in ISM
and amateur radio bands)
80% Am at 1kHz
Radiated RF
10V/m, 80% Am
IEC 61000-4-3
at 1kHz
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 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 the applicable 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 re-orienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.

Compliance level
150 kHz to 80 MHz:

Electromagnetic 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 distance calculated
from the equation appropriate for the
frequency of the transmitter.
Recommended separation distances:
where, P is the maximum output
power rating of the transmitter in
watts (W) according to the transmitter
manufacturer, d is the recommended
separation distance in meters (m). Field
strengths from fixed RF transmitters, as
determined by an electromagnetic site
survey, should be less than the
compliance level in each frequency
range. Interference may occur in
the vicinity of equipment marked with
the following symbol:
