Guidance and manufacturer's declaration - electromagnetic immunity
The Medel Smart is intended for use in the electromagnetic environment specified below.
The customer or the user of the Medel Smart should assure that it is used in such an

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 Medel Smart is used exceeds the applicable RF compliance level above, the Medel
Smart should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Medel Smart.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the Medel Smart including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
the transmitter.
Recommended separation distances
d =1.2 √ P
d =1.2√ P
80 MHz to 800MH√
d=1.2√P
800 MHz to 2.7 GHz√
d=2.3√P
where p is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended separation distance in metres (m)
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,a
should be less than the compliance level in
each frequency range.b
