Radiated RF
IEC 61000-4-3
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 viva2 is used exceeds the
applicable RF compliance level above, the MOTOmed viva2 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 viva2.
b Over the frequency range 150 KHz to 80 MHz field strengths need to be less than [
V
1] V/m.

Electromagnetic environment -
guidance
Portable and mobile RF communications
equipment should be used no closer
to any part of the MOTOmed viva 2
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 = 7/10 P = 0,35 P
for 800 MHz to 2,5 GHz
P
is the maximum output power
rating of the transmitter in watts (W)
according to the specifications of the
manufacturer and
d
is the
recommended separation distance in
meters (m).
Field strengths from fixed RF trans-
mitters, as determined by an electro-
magnetic site survey
a
should be less
than the compliance level in each
frequency range.
b
Interference may occur
in the vicinity of equip-
ment marked with the
