Appendix
Guidance and manufacturer´s declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below. The customer
and/or user of the device should assure that it is used in such an environment.
Immunity test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3

NOTE 1:
NOTE 2:
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 con-
sidered. 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 reorienting or relocating the device.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects and people.
Notes concerning the electromagnetic
environment
Portable and RF communications equipment
should be used no closer to any part of the
device, including cables, than the recom-
mended separation distance calculated from
the equation appropriate for the frequency of
the transmitter.
Recommended separation distance:
d = 0,5
d = 1,2
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).
