Electromagnetic environment –
guidelines
Portable and mobile RF
communications equipment should
be used no closer to any part of the
MOTOmed viva2 including cables,
than the recommended separation
distance calculated from the
equation appropriate for the
frequency of the transmitter:
Recommended separation distance:
d = 3,5/3 P = 1,17 P
d = 3,5/10 P = 0,35 P
for 80 MHz to 800 MHz
d = 7,0/10 P = 0,70 P
for 800 MHz to 2.5 GHz
with Pas
value for the maximum
output power rating of the
transmitter in watts (W) according
to the specifications of the
manufacturer and das the
recommended
separation distance
in meters (m).
Field strengths for fixed RF
transmitters, as determined by an
electromagnetic site survey
a
should
be less than the compliance level in
each frequency range.
b
Interference may occur in the
vincinity of equipment marked with
the following symbol.
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 MOTOmed is used
exceeds the applicable RF compliance level above, the MOTOmed should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the MOTOmed.
b) Over the frequency range 150 kHz to 80 MHz field strength need to be less than 3 V/m.
